Overview

SPPAS - the automatic annotation and analyses of speech, is a scientific computer software package developed and maintained by Brigitte Bigi, researcher in Computer Science at the "Laboratoire Parole et Langage", in Aix-en-Provence, France.

The software is primarily utilized for the annotation, segmentation, and analysis of recordings, facilitating the study of various aspects of phonetics and linguistics.

How SPPAS software can be helpful?

SPPAS is designed to assist researchers and linguists in analyzing speech data by providing a range of tools and functionalities related to phonetics, acoustics, signal processing, video processing, etc.

Among other features, SPPAS allows users to automatically annotate speech data at different phonetic levels. This annotated data can then be used to segment speech into meaningful units (e.g., phonemes, syllables, words) and align it with the original speech signal. SPPAS includes statistical tools for analyzing the data and extracting relevant information from the corpus. The software also offers a manual annotation interface and supports various annotation formats. It can export annotated data in various formats for compatibility with other speech processing and statistical analysis tools.

SPPAS allows users to customize automatic annotations to their own needs and implement custom annotation solutions.

It is a research-oriented tool and may require some familiarity with speech processing concepts and techniques.
