We will be demonstrating the ModelTalker Voice Creation System, which allows users to create a personalized synthetic voice with an unrestricted vocabulary. The system includes a tool for recording a speech inventory and a program that converts the recorded inventory into a synthetic voice for the ModelTalker TTS engine. The entire system can be downloaded for use on a home PC or in a clinical setting, and the resulting synthetic voices can be used with any SAPI compliant system.We will demonstrate the recording process, and convert the recordings to a mini-database with a limited vocabulary for participants to hear.
We will demonstrate the ModelTalker Voice Recorder (MT Voice Recorder)-an interface system that lets individuals record and bank a speech database for the creation of a synthetic voice. The system guides users through an automatic calibration process that sets pitch, amplitude, and silence. The system then prompts users with both visual (text-based) and auditory prompts. Each recording is screened for pitch, amplitude and pronunciation and users are given immediate feedback on the acceptability of each recording. Users can then rerecord an unacceptable utterance. Recordings are automatically labeled and saved and a speech database is created from these recordings. The system's intention is to make the process of recording a corpus of utterances relatively easy for those inexperienced in linguistic analysis. Ultimately, the recorded corpus and the resulting speech database is used for concatenative synthetic speech, thus allowing individuals at home or in clinics to create a synthetic voice in their own voice. The interface may prove useful for other purposes as well. The system facilitates the recording and labeling of large corpora of speech, making it useful for speech and linguistic research, and it provides immediate feedback on pronunciation, thus making it useful as a clinical learning tool.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
