You can see within official documentation the Audio formats support is:

  • Audio formats: Transcribes Free Lossless Audio Codec (FLAC), Linear 16-bit Pulse-Code Modulation (PCM), Waveform Audio File Format (WAV), Ogg format with the Opus or Vorbis codec, Web Media (WebM) format with the Opus or Vorbis codec, mu-law (or u-law) audio data, or basic audio.

Check: MIME Types for Speech to Text.

One good idea to use your mp3 audio is to convert before sending for the API.

And, depends on what you want, you can use this article. In this article, Jason shows how to use mp3 with Asterisk to send the voice audio for Speech to Text. I'm not sure if works yet.

EDIT: [10/2017]

A few days ago, Watson Speech to Text release one new version that supports mp3 input features.

Check the audio formats supported now:

Audio formats: Transcribe Free Lossless Audio Codec (FLAC), MP3 (Motion Picture Experts Group, or MPEG) format, Linear 16-bit Pulse-Code Modulation (PCM), Waveform Audio File Format (WAV), Ogg format with the Opus or Vorbis codec, Web Media (WebM) format with the Opus or Vorbis codec, mu-law (or u-law) audio data, and basic audio.
