    • A system and method for distributed speech recognition is provided. A prompt is provided to a caller during a call. One or more audio responses are received from the caller in response to the prompt. Distributed speech recognition is performed on the audio responses by providing a non-overlapping section of a main grammar to each of a plurality of secondary recognizers for each audio response. Speech recognition is performed on the audio responses by each of the secondary recognizers using the non-overlapping section of the main grammar associated with that secondary recognizer. A new grammar is generated based on results of the speech recognition from each of the secondary recognizers. Further speech recognition is performed on the audio responses against the new grammar and a further prompt is selected for providing to the caller based on results of the distributed speech recognition.
    • 提供了一种用于分布式语音识别的系统和方法。 在通话期间向呼叫者提供提示。 响应于提示,从呼叫者接收一个或多个音频响应。 通过向每个音频响应的多个次级识别器中的每一个提供主语法的非重叠部分来对音频响应执行分布式语音识别。 通过使用与该次要识别器相关联的主语法的非重叠部分的每个次级识别器对音频响应执行语音识别。 基于来自每个二级识别器的语音识别的结果生成新的语法。 对新语法的音频响应执行进一步的语音识别,并且基于分布式语音识别的结果,选择另外的提示来提供给呼叫者。

    • A computer-implemented system and method for user-controlled processing of audio signals is provided. An audio signal including a reference segment and a segment preceding the reference segment is obtained. A value q is received from a user. Audio buffers in the preceding segment are defined, each having a width of N samples and a starting point a unique number of samples away from the preceding segment's start, based on a division of N by q. One or more of the buffers are transformed into discrete Fourier transform (DFT) buffers. A signature of the signal is generated using at least a portion of the reference segment and at least one of the DFT buffers. A new audio signal is received and a DFT for the audio signal is generated. The new audio signal is determined to match the audio signal based on a comparison of the DFT to the signature.
    • 提供了一种用于音频信号的用户控制处理的计算机实现的系统和方法。 获得包括参考段和参考段之前的段的音频信号。 从用户接收到值q。 定义前面段中的音频缓冲器,每个具有N个采样的宽度,并且起始点是离开前一段的开始的唯一的采样数,基于N除以q。 一个或多个缓冲器被转换成离散傅里叶变换(DFT)缓冲器。 信号的签名使用参考段的至少一部分和DFT缓冲器中的至少一个生成。 接收新的音频信号,并产生音频信号的DFT。 基于DFT与签名的比较,确定新音频信号以匹配音频信号。

    • A computer-implemented system and method for reducing voice transcription error is provided. Audio data is received during a call and parsed into utterances. A transcribed value and confidence score are assigned to each utterance. Those utterances with low confidence scores are identified as questionable utterances. One of the questionable utterances is selected from the audio data and a pool of questionable utterances is formed. The pool includes the selected questionable utterance and other questionable utterances, from other calls, that are similar to the selected questionable utterance. A size threshold is applied to the pool of questionable utterances. All the questionable utterances in the pool are provided to at least one human transcriber when the pool fails to satisfy the size threshold. Further transcribed values are received from the transcriber for each of the questionable utterances in the pool.
    • 提供了一种用于减少语音转录错误的计算机实现的系统和方法。 音频数据在通话期间被接收并解析成话语。 转录的值和置信度得分分配给每个发音。 那些低置信度的话语被认为是可疑的话语。 从音频数据中选择可疑话语之一,并形成可疑话语池。 游泳池包括所选择的可疑话语和其他可疑话语,来自其他呼叫,类似于所选择的可疑话语。 大小阈值适用于可疑话语池。 当池不能满足大小阈值时,池中的所有可疑话语都提供给至少一个人转录器。 对于游泳池中的每个可疑话语,从抄录员收到进一步的转录值。

    • A system and method for efficiently reducing transcription error using hybrid voice transcription is provided. A voice stream is parsed from a call into utterances. An initial transcribed value and corresponding recognition score are assigned to each utterance. A transcribed message is generated for the call and includes the initial transcribed values. A threshold is applied to the recognition scores to identify those utterances with recognition scores below the threshold as questionable utterances. At least one questionable utterance is compared to other questionable utterances from other calls and a group of similar questionable utterances is formed. One or more of the similar questionable utterances is selected from the group. A common manual transcription value is received for the selected similar questionable utterances. The common manual transcription value is assigned to the remaining similar questionable utterances in the group.
    • 提供了一种使用混合语音转录有效降低转录错误的系统和方法。 一个语音流从一个电话解析为话语。 每个发音分配初始转录值和相应的识别分数。 为呼叫生成转录消息,并包括初始转录值。 将识别分数应用于阈值以将具有低于阈值的识别分数的话语识别为可疑话语。 将至少一个有问题的话语与其他电话的其他可疑话语进行比较,并形成一组类似的可疑话语。 从组中选择一个或多个相似的可疑话语。 对于所选择的类似的可疑话语,接收到常见的手动转录值。 常见的手动转录值被分配给组中剩余的类似的可疑话语。
