Best for agents with a small number of examples in intents and/or wide use of templates syntax and composite entities.

Can be used for agents with a large number of examples in intents, especially the ones using @sys.any or very large developer entities.

Not specified.

Adaptive Multi-Rate Narrowband codec.

Adaptive Multi-Rate Wideband codec.

[`FLAC`](https://xiph.org/flac/documentation.html) (Free Lossless Audio Codec) is the recommended encoding because it is lossless (therefore recognition is not compromised) and requires only about half the bandwidth of `LINEAR16`.

Uncompressed 16-bit signed little-endian samples (Linear PCM).

8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law.

Opus encoded audio frames in Ogg container ([OggOpus](https://wiki.xiph.org/OggOpus)).

Although the use of lossy encodings is not recommended, if a very low bitrate encoding is required, `OGG_OPUS` is highly preferred over Speex encoding.
