Problems solved by technology

[0004] However, in the above-mentioned phoneme database, only one type of phoneme data uttered by a specific speaker (for example, a male speaker) is registered.
Therefore, for example, in the case of outputting text information ("ちよう..." or "...みたいなあ" and other text information) that young women like to use by using synthesized voice having the above-mentioned specific reader's voice quality, the user feels that the voice quality and voice Problems with a sense of difference between content

Embodiment Construction

[0035] Embodiments of the present invention will be described below with reference to the drawings.

[0036] A. This embodiment

[0037] FIG. 1 is a diagram showing a functional configuration of a speech synthesis device 100 according to the present embodiment. In this embodiment, it is assumed that the speech synthesis device 100 is installed in a mobile terminal such as a mobile phone or PHS (Personal Handyphone System), PDA (Personal Digital Assistance), etc., which have relatively limited hardware resources, but the present invention is not limited thereto. Can be used in various electronic devices.

[0038] The input unit 210 supplies text information input via an unillustrated operation unit or the like to the text analysis unit 220 . FIG. 2 is a diagram illustrating text information.

[0039] The text content information is information indicating the content of text to be output as synthesized speech (for example, "こんにちわ"). In addition, in FIG. 2, the text content i...

Abstract

Provided is a speech synthesizer etc., capable of synthesizing speeches having various kinds of voice quality even in an environment where large restrictions are imposed on hardware resources. The speech synthesizer 100 which has one kind of phoneme data is provided with a voice quality change part 250 and a voice quality database 260. The voice quality change part 250 performs retrieval from the voice quality database 260 based upon a voice quality data number supplied from a text analysis part 220 as a retrieval key to obtain voice quality parameters. The voice quality change part 250 changes voice quality of each tone that the phoneme data obtained by a phoneme data acquisition part 230 represent based upon the acquired voice quality parameters.

Description

technical field [0001] The present invention relates to a speech synthesis device, a speech synthesis method, and a recording medium for recording a speech synthesis program for generating synthesized speech according to input text information. Background technique [0002] FIG. 17 is a diagram showing the configuration of a conventional speech synthesis device 100 that generates synthesized speech from input text information. [0003] The input unit 110 receives text information such as “こんにちわ” from an operation unit not shown, and supplies the text information to the text analysis unit 120 . The text analysis unit 120 performs word analysis, grammar analysis, etc. on the received text information by using a word dictionary, etc., and generates words representing moraic units such as "こ", "ん", "に", "ち", and "わ". The phoneme information of each phoneme and the prosodic information indicating the length, height, and strength of each phoneme are then supplied to the speech sy...
