چکیده

This paper describes the realization of a corpus-based Chinese speech synthesis system, including the corpus design and unit selection procedure. The system selects the synthesis unit according to context similarity between target unit and candidate unit. Neither prosody parameter prediction nor prosody feature modification is needed. The informal test shows that the synthesized speech is quite natural, and the speaking style of original speaker is preserved because units are all from the speaker’s utterances.

A Unit Selection-based Speech Synthesis Approach for Mandarin Chinese

The paper presents a unit selection-based speech synthesis approach for mandarin Chinese. Unit selection-based approach generates speech by selecting proper units from a speech corpus and connecting them together. In this approach, a set of features are defined to describe the speech units in the corpus and the expected units in the synthesized utterance. Based on the features, cost function is...

Corpus-based Mandarin speech synthesis with contextual syllabic units based on phonetic properties

This paper describes an improved concatenative synthesis module for a Chinese text-to-speech system [1]. The concatenated segments are on-line selected from a designed speech corpus that is precisely segmented with an improved version of HMM models. The selection criteria are the prosodic and contextual similarities between the units and the desire targets from the previous module of the TTS sy...

A Unit Selection-based Speech Synthesis Approach for Chinese Mandarin Text-to-Speech

The paper presents a unit selection-based speech synthesis approach for Chinese Mandarin. Unit selection-based approach generates speech by directly connecting pre-recorded speech units. In this approach, a corpus is used as a source unit inventory. A feature vector is defined to describe each unit. To generate speech, the feature vector of the target unit is first calculated. During synthesis,...

Hierarchical non-uniform unit selection based on prosodic structure

In speech synthesis systems based on wave concatenation, using longer units can generate more natural synthetic speech. In order to improve the usage of longer units in the corpus, this paper proposed a hierarchical non-uniform unit selection framework. Each layer included in the framework is an independent searching procedure which searches for different sized units and adopts suitable natural...
