Speech Transcription and Synthesis
Audio Toolbox™ provides examples for small-vocabulary recognition and
sound synthesis. Use pretrained models to perform general speech-to-text
transcription and text-to-speech synthesis with speech2text and text2speech. You can download Audio Toolbox extended functionality from File Exchange for text-to-speech and speech-to-text through interfaces to popular third-party
APIs. Supported APIs include Google®, IBM® Watson, Microsoft® Azure, and Amazon®.
You can interact with speech-to-text functionality graphically in the Signal Labeler app to quickly label regions of speech.
