Embodiment Construction

[0017] figure 1 A telecommunications network 100 is shown that allows endpoints 108 to exchange text and / or voice messages with each other. In general, components of network 100 implement techniques for generating a voice message from a text message such that the acoustic characteristics of the voice message correspond to the acoustic characteristics of the sound associated with the source of the text message. In the illustrated embodiment, network 100 includes data network 102 coupled to public switched telephone network (PSTN) 104 with gateway 106 . Endpoints 108 coupled to networks 102 and 104 provide communication services to users. Various servers in network 100 provide services to endpoints 108 . Specifically, the network 100 includes a speech feature vector (SFV) server 200 , a voice matching server 300 , a text-to-speech (TTS) server 400 and a unified messaging server 110 . In alternative embodiments, the functions and services provided by these various components m...

Abstract

The present invention provides a method of generating speech from a text message, the method comprising determining a speech feature vector of a sound associated with a source of the text message, and comparing the speech feature vector to a plurality of speaker models. The method also includes selecting one of the speaker models as a preferred match for the voice based on the comparison, and generating speech from the text message based on the selected speaker model.

Description

technical field [0001] The present invention relates generally to text-to-speech systems, and more particularly, the present invention relates to source-dependent text-to-speech systems. Background technique [0002] Text-to-speech (TTS) systems provide versatility in telecommunications networks. TTS systems generate audible speech from text messages such as emails, instant messages, or other suitable text. One disadvantage of TTS systems is that the sounds produced by TTS systems are often generic and not associated with the specific source providing the message. For example, text-to-speech systems can produce male voices regardless of who sent the message, making it difficult to tell whether a particular message is from a man or a woman. Contents of the invention [0003] In accordance with the present invention, a text-to-speech system provides a source-dependent presentation of a text message in a voice similar to that of the person providing the text message. This ...
