AI voice training has come a long way, making it easier than ever to create natural-sounding voices.

Continuous learning is a key feature of modern AI voice training systems. This means that the AI can learn and improve over time, adapting to new voices and accents.

With continuous learning, AI voice training can be done more efficiently, reducing the time and effort required to create high-quality voices. This is because the AI can learn from its mistakes and improve its performance with each iteration.

The result is a more accurate and natural-sounding voice, which is essential for applications like voice assistants, voiceovers, and even customer service chatbots.

Get to Know Your Customers' Experience

To truly understand your customers' needs, you need to put yourself in their shoes. This means analyzing how current communication methods impact their experiences from start to finish.

The jobs-to-be-done (JTBD) framework is a great tool for this. It's a way to discover customers' unmet needs and identify opportunities to make their lives easier through voice.

Clayton Christensen, a famed business consultant, originated the JTBD framework. It's a powerful tool for understanding customers' needs.

Creating a JTBD list for each voice use case is essential. This involves analyzing customer service call records, interviewing customer service reps, and identifying the most persistent problems and questions.

Here's an example of what a JTBD list might look like:

By analyzing this list, you can identify areas where new tools, including voice technology, could make each job quicker and easier.

Build a Prototype Based on User Interactions

Building a prototype based on user interactions is a crucial step in creating an effective AI voice system. This prototype is like a screenplay, guiding software developers who'll eventually write the code.

Your goal is to create a useful guide, not a polished product. Focus on understanding how customers will want to interact with your voice system. This means identifying the activities they'll want to undertake, the information they'll need, the friction they may experience, and the results they want to achieve.

Much of this information is likely available from your journey mapping work. You can also gather it by observing customers in their real-life context and applying conversation-modeling exercises.

To get started, think about the activities customers will want to undertake with your voice system. This could include tasks like making a purchase, checking the weather, or asking for directions.

Here are some key things to consider when building your prototype:

  • Activities: What tasks will customers want to perform with your voice system?
  • Information: What information will customers need to complete these tasks?
  • Friction: Where might customers encounter obstacles or difficulties?
  • Results: What outcomes do customers want to achieve with your voice system?

By understanding these aspects, you'll be able to create a prototype that accurately reflects the needs and behaviors of your customers.

Improving AI Voice Training

Pretesting and improving your voice model is crucial before its formal launch, as it helps achieve a high intent match rate. This involves posing a wide variety of challenges to your voice system to recreate real-world issues.

To improve your voice model, enlist the help of a voice development company like Bespoken to track performance metrics such as word error rate. Error rates of 20% or higher are possible during early rounds, but the errors often point to their solutions, which are usually more straightforward than first appear.

Here are some key considerations to keep in mind when improving your AI voice training:

  • Continuously improve as you learn more: Put your voice system in the wild, see how it performs, and iterate accordingly.
  • Use conversation-modeling exercises: Ask pairs of people to improvise dialogue between a user and the voice tool, paying attention to variations in vocabulary and sentence structure, ambiguities in user statements and questions, and points when the user would benefit from added guidance or explanation.
  • Anticipate potential user statements: Account for unanticipated user statements, such as someone responding to a text message via voice while driving, by revisiting the system design to present information more simply or giving the user slightly different options for a greater set of circumstances.

Continuously Improve as You Learn

Continuously refining and evaluating your voice tool is essential to delivering more value to users.

Enlisting the help of a voice development company like Bespoken can track performance metrics such as word error rate, a measure of how many words spoken by users the system misunderstands or misinterprets.

Don't expect market-ready results right away, as error rates of 20% or higher are possible during early rounds, which is obviously unacceptably high.

The best way to get data on your voice system is to put it in the wild, see how it performs, and iterate accordingly.

You'll have to weigh factors such as the potential impact of errors against the value you're providing when deciding when to formally launch your voice tool.

As you continually iterate your voice tool, you'll likely reveal new issues that didn't arise during initial testing, prompting continued refinement and evaluation.

Companies like Sayspring can help guide your prototyping process, and your team could build a function prototype with minimal code using advanced AI tools like GPT-4.

The goal is to continually improve your voice tool to deliver more value to users, and the only way to do that is to continuously refine and evaluate it.

By following these steps, you can ensure that your voice tool is continuously improving and delivering the best possible experience for your users.

Here are some key performance metrics to track:

  • Word error rate
  • Intent match rate
  • User satisfaction ratings

By tracking these metrics, you can identify areas for improvement and make data-driven decisions to continually refine and evaluate your voice tool.

Handling accents is another challenge, as getting the AI to understand and replicate different accents accurately can be a real challenge. This is because languages are complex and full of subtleties, so teaching an AI to speak naturally in even one language, let alone multiple, is a complicated task.

Background noise can also be a problem, confusing the AI unless it learns to handle or ignore these sounds. To overcome this, it's essential to implement noise-cancellation algorithms and train the model in varied acoustic environments.

Here are some common challenges in AI voice model training:

  • Quality and diversity of data
  • Handling accents
  • Conveying emotions
  • Background noise
  • Language nuances
  • Need for powerful computers
  • Ethical issues
  • Real-time speech
  • Flexibility and growth
  • Working with existing tech

These challenges can be addressed with strategic planning and innovative solutions. For example, you can collaborate with diverse groups to collect a broad range of voice samples, or use platforms like Mozilla's Common Voice project to access a global pool of voices.
