WAV

• Only files with a valid WAV header can be uploaded.

• Other file formats, such as MP3, are not supported.

• Use unencrypted files. Do not use encrypted audio files.

16-bit Linear PCM or G.711 is strongly recommended.

• Use of another audio format is not guaranteed to work for the voiceprint model.

• 8-bit PCM is not recommended for use due to the poor quality of the audio.

NOTE: Audio in any audio format that was not created by a suite Recorder is unlikely to result in an audio segment that can be used for voiceprint model training due to implementation differences between the audio source and the suite Recorder. Export audio from an external system as a PCM or G.711 WAV file to guarantee compatibility.

8 kHz

The voice of one person in the channel used for enrollment.

For a mono recording with multiple people speaking, use a third-party editing tool to derive an audio file containing only the voice of a single person. Imported audio is not diarized for enrollment purposes.
