Only one connection engine name can be specified. grammarFileNames: Connection engine name ### void setProfileId(String profileId) Specifies the profile ID that identifies the user using registered words. Always prefix it with a colon. For profileId, specify a string consisting of alphanumeric characters, "-" (hyphen), and "\_" (underscore). However, strings starting with "\_\_" (two underscores) are reserved by the speech recognition engine, so please do not specify strings starting with "\_\_" (two underscores). profileId: Profile ID ### void setProfileWords(String profileWords) The speech recognition server performs recognition processing using the information related to the profileWords specified here. ### void setSegmenterProperties(String segmenterProperties) Specifies parameters related to the ease of detecting speech segments and speaker diarization. For details on the parameters, please see [segmenterProperties](/amivoice-api/manual/request-parameters#segmenterproperties). ### void setKeepFillerToken(String keepFillerToken) Specifies whether to automatically delete filler words or not. keepFillerToken: `1` or `0` (Set to `0` to automatically delete filler words, `1` to keep them, default is `0`) ### void setResultUpdatedInterval(String resultUpdatedInterval) Specifies the interval for issuing recognition-in-progress events. resultUpdatedInterval: Event issuing interval (milliseconds) ### void setMaxDecodingTime(String maxDecodingTime) Specifies the maximum recognition processing time. For details, please see [maxDecodingTime](/amivoice-api/manual/request-parameters#maxdecodingtime). maxDecodingTime: Maximum recognition processing time (milliseconds) ### void setMaxResponseTime(String maxResponseTime) Specifies the maximum response time. For details, please see [maxResponseTime](/amivoice-api/manual/request-parameters#maxresponsetime). maxResponseTime: Maximum response time (milliseconds) ### void setMaxDecodingRate(String maxDecodingRate) Specifies the maximum RT. For details, please see [maxDecodingRate](/amivoice-api/manual/request-parameters#maxdecodingrate). maxDecodingRate: Maximum RT ### void setTargetResponseTime(String targetResponseTime) Specifies the target response time. For details, please see [targetResponseTime](/amivoice-api/manual/request-parameters#targetresponsetime). targetResponseTime: Target response time (milliseconds) ### void setTargetDecodingRate(String targetDecodingRate) Specifies the target RT. For details, please see [targetDecodingRate](/amivoice-api/manual/request-parameters#targetdecodingrate). targetDecodingRate: Target RT ### void setRecognitionTimeout(String recognitionTimeout) Specifies the recognition completion timeout. For details, please see [recognitionTimeout](/amivoice-api/manual/request-parameters#recognitiontimeout). recognitionTimeout: Recognition completion timeout (milliseconds) ### void setExtension(String extension) Specifies the usage aggregation tag. For details, please see [Usage Aggregation Tags](/amivoice-api/manual/billing-key). extension: Usage aggregation tag ### void setCodec(String codec) Specifies the format of the audio data to be sent. For the values to specify, please see [Audio Formats](/amivoice-api/manual/audio-format) in the development guide. This specification is required. codec: Format name ### void setResultType(String resultType) Recognition result reception type. The value to specify for the HTTP interface is "JSON". resultType: "JSON" ### void setServiceAuthorization(String serviceAuthorization) Specifies the API key. serviceAuthorization: API key ### boolean connect() Connects to the speech recognition server. ### boolean disconnect() Disconnects from the speech recognition server. ### boolean isConnected() Returns whether connected to the speech recognition server. ### boolean feedDataResume() Starts sending audio data to the speech recognition server. ### boolean feedData(byte[] data, int dataOffset, int dataBytes) Sends audio data to the speech recognition server. The feedData() method can be called multiple times between calling the feedDataResume() method and the feedDataPause() method. data: Byte array of audio data to be supplied. dataOffset: Starting offset of the audio data to be supplied. dataBytes: Number of bytes of audio data to be supplied. ### boolean feedDataPause() Completes sending audio data to the speech recognition server. When this method is called, the process is blocked until all unreceived recognition results are received. ### String getLastMessage() Retrieves the message string sent to TRACE(). ### void sleep(int timeout) Sleeps for the specified time. timeout: Wait time (milliseconds) ### void setProxyServerName(String proxyServerName) Sets the proxy server if using a proxy server. proxyServerName: Proxy settings ( \:\@\:\ )
