Tips: Computer Bio-feedback

Exclusive use of VISIPITCH – Computerized Speech Biofeedback Tool

This excellent multifaceted computer program is used for audio and visual feedback and enhances the learning and results of all of our accent programs.

Extensive Measurements of Speech and Voice Behavior

To help objectify a client’s baseline performance and subsequent change, Visi-Pitch IV extracts an extensive range of measurements relevant to speech and voice

Real-Time Pitch

Stress, timing, intonational patterns, as well as target pitch and/or amplitude values during conversational speech can be seen as they are said by the client.

Real-Time Pitch allows clients to monitor pitch and
amplitude as they speak. Speech productions can be
compared both graphically (using split screen)
and quantitatively.

Sona-Match

Multiple innovative displays of the spectral patterns of sustained phonation / pronunciation (e.g., vowels and sibilants) are offered with the Sona-Match module. These are particularly useful for articulation training, second-language acquisition, and the singing voice. Sona-Match displays these spectral parameters in real time so that it can be used for visual feedback or as a teaching tool.

Sona-Match shows the formant patterns of the speaker.
Two views can be used to enable the clinician to target desired patterns.

Sibilant training can be accomplished by placing a
target (blue outline) of the client’s best production
followed by target matching while sustaining the
desired sibilant (/s/ in this display). The red display is the

Multi-Dimensional Voice Program (MDVP)

MDVP is the most frequently cited program in professional journals for analyzing sustained phonation [voicing ] because of its robustness and accuracy with both normal and abnormal voices.

The MDVP graph provides a useful snapshot of the
client’s voice quality. Client performance (olive/red) is plotted
against normative thresholds (green) that are built
into the software.

Features

True real-time displays for visual feedback of critical speech/voice parameters
Auditory feedback tools (based on the KayPENTAX Facilitator)
Vowel and sibilant pronunciation training

Real-Time Spectrogram

The real-time performance of this module allows it to be used for selected pronunciation training and for voice “typing”.

Selected articulation therapy can be accomplished
with the Real-Time Spectrogram module. The protocol
above is for /r/ training.
