The ROI of voice experience for the industry

SPIX industry publishes the first reasoned study for the formulation of the Return on Investment of exogenous innovations in the industry.

Between Open Innovation initiatives and the forced introduction of digital innovations, the industry is expressing difficulties in formalizing and quantifying the expected Return On Investment (ROI). SPIX industry offers the first reasoned study on the calculation of the ROI expected by the introduction of breakthrough innovations in industrial processes.

Introduction on Return on Investment of innovations

The community of interest around voice technologies for industry is taking a step forward! SPIX industry is developing its network of influence around the use of voice and voice assistance in the industrial environment. Today 2,500 industrial interlocutors follow the company and participate in the animation of the current reflections on the deployment of the voice experience in the industry.

To celebrate this step, and to thank its customers and partners, SPIX industry offers the first reasoned study on the calculation of the ROI expected by the introduction of breakthrough innovations in industrial processes.

“In this article, we will see how to formulate the ROI of an exogenous innovation, from the KPIs associated with the Lean approach of the industry. It is a question here of putting into perspective the normal uncertainties linked to the introduction of any innovative technology in an industrial environment, with comprehensible, easily calculable, exhaustive and coherent improvement objectives for the industrialist”, confirms André JOLY, Managing Director.

Presentation of the article, summary

SPIX industry offers an analysis of the expected ROI following the introduction of disruptive innovations and more specifically voice technologies in industry professions. The reasons that explain the difficulties encountered by manufacturers to formalize this ROI are explained, in particular for exogenous innovations that are not in their core business. A distinction is proposed between innovations that modify industrial processes in depth, and those that optimize the place of men and women in existing processes.

The way to conduct an ROI analysis for the specific case of the introduction of voice technologies in an industrial environment is proposed. Finally, through some business examples from production and maintenance processes, the formulation of concrete operational ROIs is presented.

The article’s plan is the following :
– Introduction: innovations, industrial processes and voice technologies
– How to formalize a ROI for the industry?
Exogenous innovation, Lean, MUDA and ROI (see extract below)
– What are voice technologies for industry?
– Formalization of the ROI of the use of voice technologies
– How to evaluate the observables (KPIs) defined?
– Illustration of three industrial use cases


Exogenous innovation, Lean, MUDA and ROI

The approach to improving the productivity and efficiency of industrial organizations is formalized by a Lean approach, characterized by the fight against losses or wastes.

Originally, 7 MUDAs were defined by the Japanese Toyota to support the continuous improvement of production and industrial performance, otherwise known as Lean. An eighth MUDA was introduced later: the consideration of employees’ skills, especially blue collars, and field workers. Obviously, considering a voice innovation, this8th MUDA takes on considerable importance.

The 8 MUDAs from the Lean can be used to formalize observables adapted to the evaluation of the introduction of innovations servicing the improvement of the industrial performance.

Definition of Lean’s MUDAs

To be effective and sustainable, the processes of digitalization and innovation in industry must be part of a Lean approach. It is therefore logical, depending on the exogenous innovation considered, to formalize the expected ROI according to the MUDAs pursued. To do this, the understanding of the MUDAs and the axes of improvement of the industry, must allow us to define observables associated in the following paragraphs.

  • Over-production

Overproduction corresponds to a quantity of production higher than the demand. A task performed in addition to what is requested, or a production prior to the sales order, are also considered overproduction and therefore, waste.

  • Unnecessary stock and over-storage

Over-storage poses several problems within a company. It can be due to overproduction, untreated non-conformities, unused tools and means of production… Over-storage can lead to problems in inventory management and in the flow of the production process. Unplanned and poorly organized storage can lead to dangerous situations.

  • Unnecessary transport and travel

Whether it is information or material, all unnecessary travel is a waste and does not bring any added value. In addition, unnecessary information movements can create additional mental load and fatigue for employees. Similarly, a trip empty or a trip to find tools are losses.

  • Over-processing, complexity and unnecessary processing

A production process that is too complex in relation to customer demand, over-evaluated product quality, too much information is called over-processing. Unnecessary treatments do not bring any added value. Over-processing includes, for example, indicators that are too numerous or too complex, ranges that are complex to understand, meetings that are too long. Complexity can be a source of non-quality.

  • Unnecessary gestures and movements

On the shop floor, any unnecessary travel is a waste of energy, time, and fatigue. This phenomenon is often caused by poor ergonomics or poorly calculated organization. An operator who goes back and forth on his workstation to find the appropriate tools is an example of unnecessary movements: the equipment should be close to the work area. Nevertheless, digitalization leads to new uses at the workplace, not always compatible with operational constraints.

  • Defects, errors and scrap

When a non-conformity is produced, it necessarily constitutes a financial loss for the manufacturer. If it requires retouching or disposal, or if it represents customer dissatisfaction, then it generates a loss for the company.

  • Waiting time and delays

Waiting times and delays can come from poorly synchronized process steps, changes in series that are too long, heating time of a machine or breakdowns on the production tool. A lack of training or unclear instructions in the shop floor can lead to wait times. In addition, the need to validate a decision, which results in sending and waiting to receive a message, falls into this category.

  • Underutilized skills

Each employee has know-how, feedback, skills, creativity and team spirit that need to be put to good use during the implementation of the process and continuous improvement. Not using these abilities is a definite waste, as well as a lack of recognition and motivation among employees. This can come from too rigid management, or from a lack of training and explanations.

As part of a Lean continuous improvement process, it is therefore possible to project the effect of the planned innovations on the targeted MUDAs. This projection makes it possible to constitute a set of reliable observables, and not attackable. Indeed, being in a unitary way very linked to the targeted processes, they can hardly be questioned.

The ROI expected by the introduction of an exogenous innovation applied to an industrial process, is therefore made up of the observable KPIs associated with the targeted MUDAs.

Industrial innovations and the hunt for MUDAs

Not all innovations target MUDAs. The interest of this projection is to find the complementarities between innovations and MUDAs in a process of continuous improvement.

The table below shows the exogenous innovations mentioned in the introduction in order to project their potential effects on the MUDAs considered.

We quickly see that software innovations such as MES/FSM/CMMS and Voice Technologies are very complementary in terms of improving targeted industrial processes. Between them, they cover all 8 MUDAs considered.

Apart from Voice Assistance, very few industrial innovations target the theme “skills and know-how of operators“: the famous 8th MUDA!

What’s coming next…

In the rest of the document, we will focus on the introduction of Voice Technologies in production and industrial maintenance processes. Then we will see how to formalize the observable KPIs with the method mentioned above. These observables will then be grouped together to support the expected ROIs.

The use of Voice Technology as an example is interesting because it reflects for most manufacturers the ability or inability to evaluate an innovative investment that is not in the heart of their business.

Voice Experience by SPIX industry

SPIX industry introduces “Voice Experience” to unleash the use of voice in the industry

In today’s digital era, where technology plays a central role in every aspect of our lives, the concept of voice experience is reshaping the industrial landscape. Voice experience refers to the seamless and intuitive interaction between humans and machines through voice commands and responses (also named human-machine smart dialog). This transformative technology is revolutionizing the way we engage with industry processes, equipment, and systems.

In the industrial sector, voice experience is being leveraged to enhance worker productivity, safety, and operational efficiency. Through voice-enabled devices and applications, workers can perform tasks, access information, and control equipment using natural language commands. This hands-free and intuitive approach reduces the need for manual input, streamlines workflows, and minimizes errors.

The integration of voice experience technology in the industry offers numerous advantages. Firstly, it enables workers to access critical information, such as equipment manuals, safety procedures, or inventory data, simply by speaking their queries. This instant and contextual retrieval of information saves time and increases accuracy, empowering workers to make informed decisions on the spot.

Moreover, voice experience promotes worker safety by providing a hands-free environment. In hazardous or high-risk settings, workers can execute commands, report incidents, or request assistance without physical interaction. This not only minimizes distractions but also ensures that workers can maintain focus on their tasks while staying connected to the necessary support systems.

Additionally, voice experience enhances collaboration and communication on the shop floor. Workers can engage in real-time voice conversations with colleagues, supervisors, or remote experts, enabling efficient problem-solving and knowledge sharing. This seamless communication fosters teamwork, accelerates decision-making processes, and ultimately improves overall productivity.

The future of voice experience in the industry holds even more potential. As advancements in natural language processing, machine learning, and artificial intelligence continue to evolve, voice assistants will become even more intelligent and adaptable. They will understand complex commands, learn from user interactions, and offer personalized recommendations, further enhancing the user experience and driving operational excellence.

The limits of the digital transformation

In the wake of the digital transformation of Industry 4.0, industry decision-makers are now able to list the main problem and bottlenecks that are reducing their return on investment and preventing them from achieving their financial goals.

The main problems mentioned by digital managers and plant managers are the following:

  • The digital transformation of my production plant suffers from resistance from the workers,
  • The software already deployed (MES, CMMS, FSM) is not used to its full potential,
  • I don’t get enough data from the field, the data collected from my installations is too weak,
  • I do not get enough feedback to use the Digital Twin of my factory at the maximum of its capacity,
  • My workers waste too much time with their business software, interfaces lead to manual interventions and hand-over of data, information is lost or erroneous, non-conformities are the result. Finally, time for value creation is lost.

The introduction of digital solutions on the shop floor not only creates frustrations but may also introduce safety breaches as the workers may lose the focus on their tasks, remove their gloves, and look at a screen instead at their surrounding environment.

The introduction of voice interfaces for field operators is identified as a key solution to solve the problem, generate trust in digital systems, restore safety conditions at work, and generate more digital data from the field. SPIX industry already proved this fact with the development and adoption of its Spix.SKILLS.

SPIX is a voice assistant 100% dedicated to the field and shop floor workers of the industry. This voice assistant closes the gap between the workers (on the right) and their digital tools (on the left). It provides robust to noise voice interactions, natural language dialog functions, and private by design data management. The Spix.SKILLS are embedded, operate offline, and interface with the business software of the industrials.

Voice Experience: for what purpose?

The challenge to solve now is to give the industrials the knowhow and the confidence for them to massively deploy voice technologies on the shop floor. Nevertheless, the deployment of voice-first solutions in the industry requires to resolve a multidimensional system of constraints: coherence of the semantic, performance in the noise, data privacy, user acceptability, audio hardware, utility and usability, and the interface to the already deployed shop-floor software.

To successfully introduce the use of voice on the shop floor, “Voice Experience by SPIX industry” proposes the equivalent of the GAFAM eco-system for voice assistance, but 100% dedicated to the industry.

The “Voice Experience by SPIX industry” focuses on:

  • Industrial data management: ex. type of data needed to describe the users’ expectations, validation of the privacy of the data,
  • Assembly and validation of voice interactions: ex. assembly of the Spix.SKILLS, validation under constraints of the expected performances,
  • Interface to business software: ex. interface protocols generation for business software applications (Apriso, Maximo, SAP, QDA, SiteFlow, …).

The ambition of the “Voice Experience” is to build an eco-system, supported by on-premises solutions, to configure and validate custom voice assistants for the blue collars of the industry.

Thanks to the introduction of Voice Experience and Spix.SKILLS voice interactions on the field the European industry may restore its competitivity with the respective benefits.

  • Reduction of non-quality

Complex, critical, and rare tasks

  • Time saving

Access to information, data entry

  • Better traceability of field operation

Real-time data reports, observations, Retex

  • Increased safety of people and assets

Reminder of PPEs, alerts, reduction of security breaches

  • Improved working comfort

Reduce walking, avoid removing PPE, learning HMIs


In conclusion, voice experience is transforming the industry by revolutionizing the way workers interact with machines, systems, and processes. It empowers workers with hands-free, intuitive, and contextually relevant interactions, improving productivity, safety, and collaboration. As the technology continues to advance, embracing voice experience in the industrial setting becomes increasingly crucial for staying competitive and unlocking the full potential of human-machine interactions.

At SPIX industry, we are convinced by the development of intelligent voice assistance solutions in business verticals for the industry. On production, inspection, quality control or maintenance jobs, it is possible to assemble the necessary components of SPIX.SKILLS to ensure the usefulness, usability and acceptability of the voice services rendered to the workers. The development the “Voice Experience by SPIX industry” will help the industrials to satisfying the expected return on investment on their digital transformation.
