Non - uniform Unit Selection through Search Strategy for Blizzard Challenge 2007
نویسندگان
چکیده
This present paper describes a non-uniform unit selection synthesis system for the Blizzard Challenge 2007. Nonuniform unit is used to maximize the length of unit sequence to be selected for the target sequence. In a minor modification from the previous implementation, a different search strategy is introduced to transfer a usual phoneme-based speech system to a non-uniform unit selection system, without big changes to the voice database. The front-end analysis results, such as syllable boundary, word boundary, and prosody phrase boundary, are utilized to search from different layers. The probable best small unit instance will be selected, gradually growing up to a longer unit. It is still possible to give up an original phoneme sequence existing in the database if that sequence mismatches the context significantly.

An Overview of the VUB Entry for the 2008 Blizzard Challenge
In this paper, we describe the configuration of our synthesizer, as used for the Blizzard Challenge the first time. Two new UK English voices were built for the DSSP synthesizer, our in-house unit selection synthesizer, which uses non-uniform units and a symbolic description of target prosody. Listening tests indicate reasonable quality although there is still room for improvement.
متن کاملMulti-tier Non-uniform Unit Selection for Corpus-based Speech Synthesis
In this paper, a corpus-based speech synthesis system KB2006 was developed using the speech database provided by Blizzard Challenge 2006. We proposed a novel unit selection method called multi-tier non-uniform unit selection in our corpus-base speech synthesis system. Non-uniform unit (NUU) in our system was defined as a unit sequences that contains one or more joint phoneme units. By using CAR...

This paper describes CMU’s entry for the Blizzard Challenge 2007. Our eventual system consisted of a hybrid statistical parameter generation system whose output was used to do acoustic unit selection. After testing a number of varied systems, this system proved the best in our internal tests. This paper also explains some of the limitations we see in our techniques. The CMU system is identified...

This paper presents the version of the DRESS System that participated in the Blizzard Challenge 2008. Here we show a basic overview of the DRESS system, methodology and a description of its unit selection. We present a novel concept to increase the efficiency of the exhaustive speech unit search within the database by an unit selection model that is based on mapping analysis of the concatenatio...
