Speech to Text

The IBM Watson Speech to Text service uses speech recognition capabilities to convert Arabic, English, Spanish, French, Brazilian Portuguese, Japanese, and Mandarin speech into text.


Transcribe Audio

  • Use your microphone to record audio (Chrome or Firefox only).
  • Upload pre-recorded audio (.wav, .flac, or .opus only).
  • Play one of the sample audio files.
The returned result includes the recognized text, word alternatives, and spotted keywords. Some models can detect multiple speakers. This may slow down performance.
