WinPitch: A Multimodal Tool for Speech Analysis of Endangered Languages

Philippe Martin

CLILLAC-ARP (EA3967), France

WinPitch is a speech analysis program running on PC and Mac personal computers for acoustical analysis of speech corpora. It includes a large number of specialized functions to transcribe, align and analyze large sound and video recordings. It supports multiple hierarchical layers for segmentation (up to 96 layers), speaker lists, and overlapping speech. Various character encodings, including Unicode, are supported, with optional right to left text display for Arabic and Hebrew transcriptions. Interfaces with other popular speech analysis programs are provided, as well as standard alignment input and output in XML format. Many functions are devoted to the transcription, alignment and description of less documented languages, such as slow speed playback, programmable keyboard, automatic lexicon generation and text labeling. Various software functions are described together with their applications to the analysis of Parkateje, a Timbira language spoken in the Amazonia by about 400 speakers.
