SPPAS - MULTI-LINGUAL APPROACHES TO THE AUTOMATIC ANNOTATION OF SPEECH

Brigitte Bigi

Abstract

The first step of most acoustic analyses unavoidably involves the alignment of recorded speech sounds with their phonetic annotation. This step is very labor- intensive and cost-ineffective since it has to be performed manually by experienced phoneticians during many hours of work. This paper describes the main features of SPPAS, a software tool designed for the needs of automatically producing annotations of speech at the level of utterance, word, syllable and phoneme based on the recorded speech sound and its orthographic transcription. In other words, it can automatize the phonetic transcription task for speech materials, as well as the alignment task of transcription with speech recordings for further acoustic analyses. Special attention will be given to the methodology implemented in SPPAS, based on algorithms which are as language-and-task-independent as possible. This procedure allows for the addition of new languages quickly and for the adaptation of this tool to the user's specific needs. Consequently, the quality of the automatic annotations is largely influenced by external resources, and the users can modify the process as needed. In that sense, phoneticians need automatic tools and these tools can be significantly improved by phonetician input.
