Abstract
Description
【発明の詳細な説明】 技術分野 本発明は、テキスト音声合成方式に関する。[Detailed description of the invention] Technical field The present invention relates to a text-to-speech synthesis method.
従来技術
テキスト音声合成によって長い文章を合成する場合、合
成音は人間の発声と比べて非常に単調であり、長時間の
聴取は苦痛を伴うものであった。Prior Art When a long sentence is synthesized using text-to-speech synthesis, the synthesized speech is very monotonous compared to human speech, and listening to it for a long time is painful.
また、文字で書かれた文章には文字情報の他に。In addition to text information, written text contains text information.
傍線、傍点、かぎかっこ、太字、拡大文字、網掛け、変
形書体等の様々な強調情報が含まれるのが普通であり、
これによって重要な情報を読み手に分かりやすい形で提
供している。しかし従来のテキスト音声合成方式では、
これらの強調情報は無視して文字情報だけを入力情報と
していた。このため、出力される合成音声には強調箇所
と非強調箇所と区別はなく1合成音はさらに単調なもの
となっていた。It usually includes various emphasis information such as sidelines, dots, angle brackets, bold type, enlarged text, shading, modified fonts, etc.
This provides important information in an easy-to-understand format for readers. However, with conventional text-to-speech synthesis methods,
This emphasized information was ignored and only character information was used as input information. For this reason, there is no distinction between emphasized parts and non-emphasized parts in the output synthesized speech, and one synthesized speech becomes even more monotonous.
目 的
本発明は、上述のごとき実情に鑑みてなされたもので、
特に、音声のテキスト合成において、単調になりがちな

In particular, in text synthesis of speech, the aim is to make the synthesized speech, which tends to be monotonous, easier to listen to by emphasizing the important information contained therein.

ある。以下、本発明の実施例に基いて説明する。Structure In order to achieve the above object, the present invention extracts morphological information from an input text by morphological analysis processing, and based on this extracts phonological symbol strings according to phonological rules and prosodic symbol strings according to prosodic symbol derivation rules, and prepares them in advance. In a text-to-speech synthesizer that reads out parameter sequences of speech segments according to phonetic symbol strings, connects them according to connection rules, and adds prosody from prosodic symbol strings according to prosodic rules, it is necessary to use a text-to-speech synthesizer that reads out parameter sequences of speech segments according to phonetic symbol strings, connects them according to connection rules, and adds prosody from prosodic symbol strings according to prosodic rules. When the character string emphasized by the emphasis information is uttered, the prosody of the synthesized speech is changed. Hereinafter, the present invention will be explained based on examples.

太字。In a text-to-speech synthesizer that reads out a parameter sequence of speech segments prepared in advance according to a phonetic symbol string, connects them according to a combination rule, and adds prosody using a prosodic symbol string according to a prosodic rule, it is possible to detect some emphasis information in the input text. If included, the prosody of the synthesized speech is changed when the character string emphasized by the emphasis information is uttered. For example, it changes the prosody of the synthesized voice.

In the embodiment shown in FIG. 2, the fundamental frequency of the part emphasized by the emphasis information is given a certain bias with respect to that of the non-emphasized part. It was made more expensive. In addition, the embodiment shown in FIG.
The embodiment shown in FIG. 4, which increases the power of a part emphasized by emphasis information with a certain bias compared to that of a non-emphasis part, increases the power of a part emphasized by emphasis information. It is slower than that of the emphasized part, that is, the duration length of each phoneme of the emphasized part is longer than that of the non-emphasized part.
