Google AI Releases WAXAL: Multilingual African Speech Dataset for ASR and TTS
Google researchers have released WAXAL, an open multilingual speech dataset covering 24 African languages to address the data gap in speech technology for low-resource languages.
Why it matters
Improving speech technology for underrepresented languages is crucial for increasing digital inclusion and accessibility in Africa and other regions.
Key Points
- 1WAXAL dataset covers 24 African languages
- 2Aims to improve Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) models for underrepresented languages
- 3Addresses the data distribution problem in speech technology
Details
The WAXAL dataset is an effort by Google and collaborators to improve speech technology for African languages, which have been historically underrepresented in open speech corpora. The dataset covers 24 languages and is intended to train better Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) models for these low-resource languages. This helps address the data distribution problem in speech technology, where systems have advanced rapidly for high-resource languages but struggle with many African and other minority languages due to lack of training data.
