PicoVoice offline Voice AI engine gets free tier for up to 3 users

PicoVoice offline Voice AI engine has now a free tier that allows people to create custom wake words and voice commands easily for up to three users on any hardware including Raspberry Pi and Arduino boards.

I first learned about PicoVoice about a year ago when the offline voice AI engine was showcased on a Raspberry Pi fitted with ReSpeaker 4-mic array to showcase the company’s Porcupine custom wake word engine, and Rhino Speech-to-Intent engine. The demo would support 9 wake words with Alexa, Bumblebee, Computer, Hey Google, Hey Siri, Jarvis, Picovoice, Porcupine, and Terminator.

More importantly, the solution allows you to easily create your own custom words in minutes from a web interface by simply typing the selected wake word, with no need for hundreds of voice samples or waiting weeks to get it done. So I tried “Hey You” first, but I was told it was too short, so I changed that to “dear master” and could try it on after only 20 minutes on my Ubuntu 20.04 laptop using Firefox browser. But at the time, it was only available for Windows, Linux, or macOS, and Arm Linux platforms required a commercial license.

But this has just changed, as Picovoice Free Tier enables anyone with an email address or a GitHub account to use Picovoice for free, even commercially, for up to three users. The offer includes Porcupine wake word and Rhino Speech-to-Intent engines, as well as the new Cobra VAD engine. The company says “No credit card required, no hidden fees”. Let’s check it out.

Porcupine Wake Word CreationI’ll use “Hello Omicron” and select the English language, but PicoVoice also supports German, Spanish, and French. After I click the button “Train Wake Word”, I’m asked to select the platform…

The good news is we’re not limited to x86 platforms anymore, Raspberry Pi, BeagleBone, Nvidia Jetson, iOS & Android devices. macOS arm64, and even Arm Cortex-M targets (e.g. Arduino Nano 33 BLE Sense) are supported in the free tier. Not sure about other Arm Cortex-A Linux platforms though, maybe selecting “Raspberry Pi” would work? One limitation is that you can only train three wake words per month, but that should be enough for most personal projects.

PicoVoice Console Custom Wake WordThis time around, it only took a few seconds after clicking on “Train Wake Word”, to get the file required for Raspberry Pi. I don’t have hardware setup for this, so I may try it in more detail another day, but I could still confirm “Hello Omicron” worked just fine in Firefox using my laptop’s microphone. Read the documentation to learn how to get started.

What if you need to handle more than three active users per month? There’s a paid option for $899 per month for up to 1,000 active users. I’m not quite sure how it compares to competitors since pricing is not usually made public. Custom pricing is also offered for companies requiring more than 1,000 users.

There’s no such thing as “Free” offline voice AI. Spying on what you say and do is the product.

I totally agree with you Jean-Luc. I think that the vast majority of innovative applications to come in this area will be designed at home by end users themselves, just like ESP8266 and ESP32 success was born. It’s the right approach from such a company to propose something for free for small scale usage and encourage innovation. If even 0.01% of their users create a new product from that, it can be beneficial to them and justifies the “free” approach.

I don’t think many tinkerers are interested in using proprietary trial software in there projects.

@david you could not be more wrong even the new Pixel phones are offline KWS & ASR. There are many free offline software sources for KWS, ASR & KWS. The TensorTPU heralded by Google is to train local incremental models to garner user accuracy. What is missing though is free audio preprocessing of AEC, Beamforming, Source Separation & Noise suppression. What is available doesn’t work that well and many platforms don’t have a full audio pipeline that can provide good working recognition in noise. Picovoice is a KWS that is offline but does have a online training service. There is… Read more »

Any one remembering snips? It was “even” (partly) open source… still it was not FOSS!
