Speech Input - Amazon Transcribe

Speech Input

To transcribe an audio file, you use a transcription job. You store the file as an object in an Amazon S3 bucket. The input file must be:

  • In FLAC, MP3, MP4, or WAV file format

  • Less than 4 hours in length or less than 2 Gb of audio data

Specify the language and format of the input file.

For best results:

  • Use a lossless format, such as FLAC or WAV, with PCM 16-bit encoding.

  • Use a sample rate of 8000 Hz for telephone audio.
