Embodiment Construction

[0016] As briefly mentioned above, human speech includes not only the substance (what words and sounds are produced), but also information about how the words and sounds are produced. Typically, a set of parameters (prosodic parameters) at least partially describe how a word or sound is spoken and what it sounds like. Examples of prosodic parameters are pitch, energy and timing. Better use of prosodic content can result in more natural and intelligible synthesized speech, a useful feature in modern communication systems such as mobile phones using synthesized audio interfaces.

[0017] A telephone device in accordance with the present invention uses speech synthesis circuitry, logic and executable coded instructions to produce an audible signal provided through its speaker output. By extracting and using prosodic features of words spoken by the user to synthesize and produce audible output, the telephony device synthesizes high-quality realistically-voiced speech that sounds ...

Abstract

A method and apparatus for synthesizing an audible phrase (word) comprising capturing an utterance, which may be a word, and extracting prosodic information (parameters) from the utterance, and then applying the prosodic parameters to the synthesis (nominal ) words to produce prosodic imitation words corresponding to the uttered and nominal words.

Description

technical field [0001] The present invention relates to voice-enabled communication systems. Background technique [0002] Many mobile phones (referred to here as including data processing and communication devices capable of performing at least telephony or voice communication functions) are equipped with a voice-assisted interface feature that enables a user to access a function by speaking words to invoke that function. A familiar example is voice dialing, whereby a user speaks a name or other stored phrase to a phone, and the phone responds by dialing the number associated with that name. [0003] To verify that the number to be dialed or the function to be invoked is indeed what the user intended, the mobile phone can display a confirmation message to the user, allowing the user to proceed if correct, or to abort if incorrect. Audible and / or visual user interfaces exist for interacting with the mobile telephony device. Audible confirmations and user interfaces allow f...
