方法详细资料

getVadEndWaitMs

public int getVadEndWaitMs()

Obtains the post-VAD threshold. VAD stands for voice activity detection.

If the silence period in the middle of a user's utterances reaches the post-VAD threshold, speech recognition will stop.

返回:

Returns the post-VAD threshold, in milliseconds.

从以下版本开始:

3

setVadEndWaitMs

public void setVadEndWaitMs(int vadEndWaitMs)

Sets the post-VAD threshold.

If the silence period in the middle of a user's utterances reaches the post-VAD threshold, speech recognition will stop.

参数:

vadEndWaitMs - Indicates the post-VAD threshold. The value ranges from 500 to 10000 (default value: 2000}, in milliseconds. If this parameter is set to a value beyond this range, the valid post-VAD threshold set most recently will be used.

从以下版本开始:

3

getVadFrontWaitMs

public int getVadFrontWaitMs()

Obtains the pre-VAD threshold.

If the silence period before any utterances are captured reaches the pre-VAD threshold, speech recognition will stop.

返回:

Returns the pre-VAD threshold, in milliseconds.

从以下版本开始:

3

setVadFrontWaitMs

public void setVadFrontWaitMs(int vadFrontWaitMs)

Sets the pre-VAD threshold.

If the silence period before any utterances are captured reaches the pre-VAD threshold, speech recognition will stop.

参数:

vadFrontWaitMs - Indicates the pre-VAD threshold. The value ranges from 500 to 10000 (default value: 4800), in milliseconds. If this parameter is set to a value beyond this range, the valid pre-VAD threshold set most recently will be used.

从以下版本开始:

3

getTimeoutThresholdMs

public int getTimeoutThresholdMs()

Obtains the ASR timeout threshold.

返回:

Returns the ASR timeout threshold, in milliseconds.

从以下版本开始:

3

setTimeoutThresholdMs

public void setTimeoutThresholdMs(int timeoutThresholdMs)

Sets the ASR timeout threshold.

The input parameter timeoutThresholdMs takes effect in AsrClient.startListening(AsrIntent) but not in AsrClient.init(AsrIntent, AsrListener).

参数:

timeoutThresholdMs - Indicates the ASR timeout threshold. The value ranges from 1 to 20000 (default value: 20000), in milliseconds. If this parameter is set to a value beyond this range, the invalid ASR timeout threshold set most recently will be used.

从以下版本开始:

3

getFilePath

public String getFilePath()

Obtains the path of an audio file.

返回:

Returns the audio file path.

从以下版本开始:

3

setFilePath

public void setFilePath(String filePath)

Sets the path of the audio file to be recognized.

To ensure that ASR can take effect on audio files, you must call setAudioSourceType(ohos.ai.asr.AsrIntent.AsrAudioSrcType) with AsrAudioSrcType#ASR_SRC_TYPE_FILE as the input parameter before calling AsrClient#init(AsrIntent, AsrListener) to initialize the ASR engine.

参数:

filePath - Indicates the path of the audio file to be recognized.

从以下版本开始:

3

getAudioSourceType

public int getAudioSourceType()

Obtains the audio source type.

返回:

Returns the audio source type represented by an integer, as defined in AsrAudioSrcType.

从以下版本开始:

3

setAudioSourceType

public void setAudioSourceType(AsrIntent.AsrAudioSrcType audioSourceType)

Sets the audio source type.

参数:

audioSourceType - Indicates the audio source type. The default value is AsrAudioSrcType#ASR_SRC_TYPE_FILE.

从以下版本开始:

3

getEngineType

public int getEngineType()

Obtains the ASR engine type.

返回:

Returns the ASR engine type represented by an integer, as defined in AsrEngineType.

从以下版本开始:

3

setEngineType

public void setEngineType(AsrIntent.AsrEngineType engineType)

Sets the ASR engine type.

参数:

engineType - Indicates the ASR engine type. The default value is AsrEngineType#ASR_ENGINE_TYPE_LOCAL.

从以下版本开始:

3
