Simple Method of Determining the Voice Similarity and Stability by Analyzing a Set of Very Short Sounds
This paper presents a simple method of determining the voice similarity by analyzing a set of very short sounds. A large number of pitch-length sounds were extracted from natural voice signals from different realizations of open vowels ’a’ and ’o’. The voice similarity was defined as the sum of single elementary similarities of short sound pairs. This method is oriented to the microphonemic speech synthesis based on waveform concatenation, and it could help to limit the time needed for database collection. This simple and low computational load speech synthesis method can be applied in small portable devices and used for the rehabilitation of speech disabled people.
