Abstract:
1. A method for text to speech conversion, comprising: parsing, with at least one processor, input text to obtain descriptive prosody annotations of the text based, at least in part, on a text-to-speech model generated from a first corpus, wherein the descriptive prosody annotations include a prosody structure of the text, wherein the prosody structure of the text is associated with an initial speech speed, and wherein said prosody structure includes information selected from the group consisting of prosody word information, prosody phrase information, and intonation phrase information; adjusting the prosody structure of the text based, at least in part, on a target speech speed for speech to be synthesized corresponding to the input text, wherein the target speech speed is different than the initial speech speed; determining at least one prosody parameter of the text based, at least in part, on the adjusted prosody structure of the text; and synthesizing speech corresponding to said input text based, at least in part, on said at least one prosody parameter of the text.
