Mozilla right this moment launched the most recent model of Common Voice, its open supply assortment of transcribed voice knowledge for startups, researchers, and hobbyists to construct voice-enabled apps, companies, and gadgets. Common Voice now accommodates over 7,226 complete hours of contributed voice knowledge in 54 completely different languages, up from 1,400 hours throughout 18 languages in February 2019.
Common Voice consists not solely of voice snippets, however of voluntarily contributed metadata helpful for coaching speech engines, like audio system’ ages, intercourse, and accents. It’s designed to be built-in with DeepSpeech, a collection of open supply speech-to-text, text-to-speech engines, and educated fashions maintained by Mozilla’s Machine Learning Group.
Collecting the over 5.5 million clips in Common Voice required a number of legwork, particularly as a result of the prompts on the Common Voice web site needed to be translated into every language. Still, 5,591 of the 7,226 hours have been confirmed legitimate by the challenge’s contributors to date. And in response to Mozilla, 5 languages in Common Voice — English, German, French, Italian, and Spanish — now have over 5,000 distinctive audio system, whereas seven languages — English, German, French, Kabyle, Catalan, Spanish, and Kinyarwandan — have over 500 recorded hours.
Today additionally noticed the discharge of Mozilla’s first-ever knowledge set goal phase, which goals to gather voice knowledge for particular functions and use circumstances. This phase consists of the digits “zero” via “nine” in addition to the phrases “yes,” “no,” “hey,” and “Firefox,” spoken by 11,000 individuals for 120 hours collectively throughout 18 languages. Previously, Common Voice product lead Megan Branson mentioned it could be used partly for “Hey Firefox” wakeword testing.
“This segment data will help Mozilla benchmark the accuracy of our open source voice recognition engine, DeepSpeech, in multiple languages for a similar task and will enable more detailed feedback on how to continue improving the dataset,” Branson wrote in a blog post. “With contributions from all over the globe, you are helping us follow through on our goal to create a voice dataset that is publicly available to anyone and represents the world we live in.”
The Common Voice refresh follows a big replace to DeepSpeech that included one of many quickest open supply speech recognition fashions up to now. The newest model added help for TensorFlow Lite, a distribution of Google’s TensorFlow machine studying framework that’s optimized for compute-constrained cell and embedded gadgets, and reduce down DeepSpeech’s reminiscence consumption by 22 occasions whereas boosting its startup velocity by over 500 occasions.
Both Common Voice and DeepSpeech inform work on Mozilla initiatives like Firefox Voice, a browser extension that provides voice recognition help to Firefox. Currently, Firefox Voice can perceive instructions like “What is the weather” and “Find the Gmail tab,” however the objective is to facilitate “meaningful interactions” with web sites utilizing voice alone.
