L_ASREngineAudioProperties

Summary

The L_ASREngineAudioProperties provides information about the supported speech recognition engine's audio properties, required by the loaded runtime.

Syntax

struct L_ASREngineAudioProperties 
{ 
   L_UINT StructSize; 
   L_UINT SamplingRate; 
}; 
typedef struct L_ASREngineAudioProperties L_ASREngineAudioProperties; 

Members

StructSize

Size of this structure, in bytes. Use the sizeof operator to calculate this value.

SamplingRate

Indicates the number of samples per second (Sample Rate).

Comments

Considered to be main properties, among others, are the number of channels and the sampling rate. However, the following properties are required for the supported engine to process a wave file:

1. Pulse-Code Modulation format (PCM wave file)
2. Mono
3. 16-bit
4. Sample rate: 16000 or 8000 Hz

Usage

• L_ASREngine_GetAudioProperties
