Parameters

hport

The port's handle.

Remarks

Each LV_SpeechPort supports 64 separate voice channels. Each channel has its own separate storage for decode data, so once the call is made, the client application can release its own copy. LoadVoiceChannel will accept the audio data and prepare it for decoding.
