No limitation on duration or signal quality, Vocalise. Spectral and phonetic feature analysis. Semi or fully automatic comparisons. Command-line and API versions available. Calculate Vocalise ratios that can be used in forensic reports using Bio-Metrics. State-of-the-art algorithms. Read Vocalise Flexible speaker feature extraction options. Choice of spectral and phonetic features Spectral features Spectral features are descriptors of the frequency characteristics that are automatically extracted from a speech sample over short time windows, and are the most commonly used feature-type in speech and speaker recognition.
Advanced features. Playback and visualisation: Choose between Waveform and Spectrogram view. Drag-and-drop: Specify a directory or folder which contains the files to compare against, or drop the files into the interface for comparison. Optimised to run quickly on multi-processor machines: Allows for quick comparison of files using both spectral and Vocalise features.
If desired, create your own custom session, from scratch or from an existing session. Unique capability of using features traditionally used in forensic phonetic acoustic analysis: Includes pitch, formants, as well as spectral features such as Mel Frequency Cepstral Coefficients MFCCs.
Apply automatic speaker recognition techniques to phonetic features: Modelling of long-term formant distributions and formant dynamics with Universal Background Models UBMs and GMMs, as well as with state-of-the-art i-vector and x-vector approaches. Result presentation: After running a comparison, the audio files are sorted by comparison score in decreasing order, with the most similar file appearing at the top of the list.
Exporting output scores: Save, edit, and copy files, then export scores into the Bio-Metrics Software Vocalise analysis. Publications by OWR and some of our users.
