[iskng]

OpenAI session error: Invalid value: 'g711-ulaw'. Supported values are: 'pcm16', 'g711_ulaw', and 'g711_alaw'.

Spec input_audio_format string

Optional The format of input audio. Options are pcm16, g711_ulaw, or g711_alaw. For pcm16, input audio must be 16-bit PCM at a 24kHz sample rate, single channel (mono), and little-endian byte order.
