Accented English Speech Recognition Data

From:Datatang Date:2023-04-02

The importance of speech to human-computer interaction is unquestionable. Letting machines "understand" human language is the goal that speech recognition technology has been committed to achieving since its birth.

Studies have shown that for non-native English speakers, such as Spanish or Chinese as their first language, the recognition accuracy of English spoken by Google Home or Amazon Echo is 30% lower than that of native American accents. Solving the problem of English accent recognition has become the focus of competition in intelligent speech recognition, and major well-known AI companies are trying to overcome this "difficulty".

What is so difficult about accented English recognition? In theory, as long as there is enough data for the machine to train, it is not a problem for AI to recognize any language or accent.

That is to say, an excellent speech recognition model requires training with a large amount of labeled data: first, it needs to collect the speech content; second, it needs to manually mark the speech and transcribe the speech content into text; finally, the algorithm logically associates the recognized text content with the corresponding audio.

Datatang, as the world's leading AI data service provider, relies on its own data resources, technical advantages and rich data processing experience to overcome the difficulties of Speech Recognition Data collection. Since its establishment in 2011, Datatang has accumulated more than 20,000 hours of accented English datasets.
