About
PhonaLab is a cloud-based set of acoustic voice analysis tools designed for speech-language pathologists and voice clinicians. It supports clinical documentation and workflow by providing research-grade measurements validated against Praat, including measures such as F0, jitter, shimmer, HNR, CPP/CPPS, and multiparametric indices like AVQI and ABI. Users can upload recordings in common formats (e.g., WAV, MP3, M4A) without conversion, view analyses such as pitch tracking, spectrograms (wideband and narrowband) with aligned waveforms, and spectral measures like LTAS and Alpha Ratio, and export professional PDF reports for documentation and sharing. The site emphasizes privacy-sensitive operation (“HIPAA aware by design”) by avoiding storage of patient identifiers and analysis results. PhonaLab states it is for educational and clinical documentation only and does not provide diagnosis or medical advice.
