    • A method and system for communicating information to a telephony user in response to a request for the information from the telephony user includes a text data source having text documents and a voice application operable with the text data source for retrieving a text document related to the requested information. A text-to-speech (TTS) manager divides the text document into text document segments. TTS engines convert the text document segments into speech segments. Each text document segment is converted into a speech segment by one TTS engine. A buffer reassembles the speech segments in the proper order and then delivers the speech segments to the user. The TTS manager divides the text document as a function of the rate at which speech segments are delivered to the user such that the speech segments are delivered from the TTS engines to the buffer and from the buffer to the user continuously.
    • 响应于来自电话用户的信息的请求而向电话用户传送信息的方法和系统包括具有文本文档的文本数据源和可与文本数据源一起操作的语音应用程序,用于检索与请求的文本文档相关的文本文档 信息。 文本到语音(TTS)管理器将文本文档划分为文本文档段。 TTS引擎将文本文档段转换为语音段。 每个文本文档段由一个TTS引擎转换成语音段。 缓冲器以适当的顺序重新组合语音段,然后将语音段传递给用户。 TTS管理器根据语音片段传送给用户的速率将文本文档划分,使得语音段从TTS引擎传送到缓冲区,并从缓冲区传送到用户。
