Picovoice researchers continuously improve techniques and frameworks used to train algorithms. Picovoice applies transfer learning, hardware-aware training, and neural compression principles, resulting in efficient models competing with cloud-dependent AI models.

It depends on your tech stack and design. Given the number of engines Picovoice offers and the platforms it supports, it's hard to communicate one number. We encourage developers to do their own tests and evaluations in their real environments.

Yes, Picovoice technology works well across accents and dialects. The best way to learn about it is to test Picovoice engines with your dataset. Picovoice offers a Free Plan that allows enterprises to evaluate and become familiar with the technology, as well as a Foundation Plan to run thorough tests before committing to an Enterprise Plan.

Picovoice aims to provide realistic benchmarks by leveraging various accents and noise. Yet, we encourage developers to test the engines in their real-world environments.

Picovoice engines expect audio with a 16kHz sampling rate. PSTN networks usually sample at 8kHz. It is possible to upsample but the frequency content above 4kHz is gone, and performance will be suboptimal. It is possible to train acoustic models for telephony applications for enterprise customers. Engage with Picovoice Consulting to find the best solution that works for you.

Picovoice software expects a 16kHz sampling rate. You will need to downsample. Typically, operating systems or sound cards (Audio codecs) provide such functionality; otherwise, you will need to implement it.

Picovoice software expects a 16kHz sampling rate, as it strikes a balance between quality and file size, used in voice commands and speech recognition technologies. At 16kHz, audio files are small enough to store and transmit while offering reasonable audio quality. Secondly, the human voice's most critical frequencies lie between 300Hz and 3400Hz. The Nyquist-Shannon sampling theorem states that a sampling rate of at least twice the highest frequency is required for accurate signal representation. 16kHz is more than twice 3400Hz and sufficient for processing the human voice. That's why 16kHz has become a standard in applications using human speech and voice.

There are several factors that affect the performance of voice AI engines: quality of audio data, environment - noise, echo, reverberation, tech stack, and design.

You can leverage the self-service Picovoice Console to fine-tune voice AI models or engage with Picovoice Consulting for further improvement.

See how to fine-tune models on the Picovoice Console:

• Custom Wake Words
• Custom Voice Commands
• Custom Speech-to-Text

Custom speech recognition models are created for specific tasks, specific use cases, and sometimes for specific environments. General-purpose models are jacks-of-all-trades and masters-of-none. For example, if you need a medical dictation app, you need a fine-tuned speech-to-text to be able to capture the jargon correctly. If you're building a sales enablement app, just like you train your salesforce to learn about your product names, you should adapt the general speech recognition model accordingly.

You can engage with Picovoice Consulting to discuss the opportunity.

Picovoice voice AI engines support the most popular and widely-used hardware and software out-of-the-box - from web, mobile, desktop, and on-prem to private cloud. However, there may be certain chipsets we do not currently support. (There are so many of them, yet only so much time and money, making it impossible to support everything.) You can engage with Picovoice Consulting and get any Picovoice voice AI engine ported to the platform of your choice.

Picovoice voice AI engines support the most popular and widely used SDKs. If you need another SDK, you can check our open-source SDKs and build it yourself or contact Picovoice Consulting. Picovoice Consulting experts can create a public or private library for the SDK of your choice and maintain it.

Picovoice engines have a lexicon of hundreds of thousands of words in their lexicons. However, there might be some special words we missed. You can reach out to your Picovoice contacts when you become a Picovoice Enterprise Plan customer to get a new word added to the lexicon.

You can create a GitHub issue under the relevant repository/demo.

Enterprises face several challenges while building PoCs. Finding a talent experienced in machine learning is one of the biggest challenges to start with. We learned this the hard way, and experience it every day. On top of it, executives and clients may have unrealistic deadlines.

Experts at Picovoice Consulting help enterprises build PoCs, develop their AI strategy, and work with them hand-in-hand offering the guidance they need.

The answer is “it depends”. Voice AI is complex technology and building products for production requires diligent work. It depends on your use case, other tools, and the tech stack used, along with hardware and software choice. Given the variables, it can be challenging. You can experiment different scenarios leveraging Picovoice's Free resources or engage with experts from Picovoice Consulting to find the best approach to deploying language models for production.
