BioVoice: A multipurpose tool for voice analysis

• BioVoice, a user-friendly software tool for the acoustical analysis of human voice is presented. BioVoice performs both time and frequency analyses, estimating more than 20 parameters. Basic parameters are computed as well new ones specifically developed newborn cry singing analysis. Examples presented showing capabilities also compared to another existing tool. This paper introduces voice. It estimates with advanced robust techniques different vocal emissions, from adult singer. detecting number, length, percentage voiced unvoiced segments computing fundamental (F0), formant frequencies (F1-F3), noise level, jitter. The computes melodic shape F0 out 12 basic shapes allows performing perceptual in child In case, formants up F5 quality ratio concerning vibrato its regularity.
