Automate labeling and tagging of speech recordings, assess the performance of DSP pipelines for voice and speech enhancement, run text analytics on voice recordings, and more.
This entry enables you to convert sampled speech recordings available as MATLAB vectors into strings using a single function call. Starting from MATLAB release R2019b, this also enables you to perform speech transcription interactively using Audio Labeler app.
You will need a license of Audio Toolbox, an internet connection, and an active subscription to a speech-to-text service of your choice – Google™ Cloud Speech-to-Text API, IBM™ Watson Speech to Text API, or Microsoft™ Azure Speech Services API.
Please check out the Examples tab for detailed instructions on how to get started.
