 lingWAVES
Voice Clinic Suite Pro
lingWAVES SLT/SLP Suite Pro offers powerful basic and
extended components
for speech and language assessment and biofeedback. The set includes a
high quality voice recorder with extended voice analysis, a comfortable
patient/client database, an professional and up-to-date biofeedback system for
voice and speech, a new motor speech disorder and the latest generation of voice quality assessment. lingWAVES Basis with Voice Recorder, Client Database and Voice
Disorder Index
Voice Recorder
 SLP/SLT/Voice
Clinic service relies on
documenting information on therapy progress.
An excellent way of documenting and archiving patient data is to record
part or all of the examination/ therapy session. The main advantage of
recording is that it affords the opportunity to
diagnose the voice trouble more precisely, to
compare the voice quality of the patient at
the beginning, during and at the end of the therapy session and to
review the evaluation later. lingWAVES Voice Recorder deals with this
task in a modern and simple way.
The voice recorder also includes cut, copy, paste and delete functions
for recordings.
Client/Patient Manager
 lingWAVES
offers two modes of operation for carrying out lingWAVES sessions. You
can either work file oriented which would mean that you open analysis
files on the menu and save them under an appropriate name of your
choice, or you can work client oriented out of the
client manager. The difference is that you have to create a
client/patient in the client manager before you can carry out test
activities connected to this patient. The files will be automatically
saved. You do not have to take care of data management. The program will
do it for you.
Standard Voice Analysis
This set includes standard acoustical voice analysis
like spectrogram, energy and pitch (fundamental
frequency). It is easy manageable to add voice analysis to each
recorded voice signal. The whole analysis will automatically be saved in
a project file. This means that you can reopen the voice record with the
same analysis you have done before.
.
Print out the whole analysis and/or save the analysis as
bitmap for further documentation (e.g. in word processing programs).
Extended Voice Analysis
 For
more scientific purpose this suite comes with extended voice analysis
features: spectrography with formant tracking/energy/F0, jitter, shimmer
for long term analysis and LPC, AMDF, Cepstrum and Autocorrelation for
short term analysis.
You can add multiple voice analysis windows to a signal
(e.g. Spectrography, F0, jitter, ...)
Voice Disorder Index (VDI)
 The Voice Disorder Index (VDI)
or Stimmstörungsindex (SSI) has been established as a reliable tool for describing voice-dependent
quality of life. The sole purpose of the VDI is to provide some
preliminary information regarding the severity of voice problem as it
relates to the most common activities in daily life. The VDI/SSI- based „VHI-korr” provides good international
comparability of voice disorders with VHI and allows to maintain the
common use of SSI in daily clinical routine. Voice Disorder Index/Voice
Handicap Index correlation r=0.98.
lingWAVES Vospector
Instantaneous and Reliable Voice Analysis
 lingWAVES Vospector provides a set of
clinically useable quantitative acoustic analyses that reflect important
aspects of voice.
lingWAVES Vospector calculates additional parameters of vocal fold
behavior. lingWAVES Vospector standard measurements made on sustained vowels
include minimum, maximum, average and standard deviation for
fundamental
frequency, jitter (period to period variation in the fundamental
frequency), shimmer (period to period variation in the amplitude) and
GNE (glottal to noise excitation ratio).
Acoustic Correlates of Perceptual Attributes of Voice
according to the RBH/ORB Rating System
Separate measurements add up to yield
further voice parameters like irregularity,
noise and overall severity
of dysphonia that can be regarded as objective counterparts to R
(roughness), B (breathiness) and H (hoarseness) components of the RBH/ORB
(Cape-V) rating system for the perceptual evaluation of dysphonia.
Biofeedback
lingWAVES Theravox - Voice and Speech
TheraVox is a wonderful computer speech therapy tool made with
affection and care. It is a product consisting of a series of exercises
for logopedic/speech therapy in which voice and speech elements like
voicing/voice onset, loudness, articulation/coarticulation and prosody
are transformed into real time graphics. The patient gets a visual
feedback for qualitative and quantitative attributes of his voice, which
is of crucial importance for enhancing self-monitoring skills within the
context of speech therapy.
Real Time Spectrogram
 The
Real Time Spectrogram provides a dual-screen with time signal display
and spectrogram analysis during signal recording. Spectrogram parameters
such as wide to narrow-band, color, frequency range and display
parameters such as dual or one-screen may be adjusted. In the one-screen
mode you can show a full size spectrogram with a time axis adjustable
from 5 to x hundred seconds. The recording can partly or full saved as
sound file for further analysis. The Real Time Spectrogram session can
be saved as project file, showing the same display after reloading.
This real time display is ideal for therapy and clinical
biofeedback showing all kinds of sounds and other acoustical parameters
of voice and speech. Spectral analysis is especially
recommended for use improving accuracy of voice and speech elements in
clients with hearing impairments and is ideal for ambitious therapists.
Multi Real Time Display
 Multi
Real Time is an extended Real Time Spectrogram showing additionally
fundamental frequency/pitch and energy during signal recording. Multi
Real Time shows acoustic parameters such as time signal, spectrogram,
pitch and energy during voice and speech production without time delay
in real time. In many cases this tool is used to compare vocalization
and pronunciation between speech therapist (target) and patient (trial)
with the benefit of both graphically and auditory feedback.
 Motor Speech Disorder Assessment
Motor
Speech Disorder Assessment (MSDA) is a new technology tool to analyze
and show voice and speech parameters describing motor speech disorders.
The new technology allows to analyze recorded speech within seconds. The
result is a understandable report of numerical parameters at a glance.
Voice Diagnostic Center - Voice Range Profile
 The
lingWAVES VDC is a combined analysis tool for the measurement of
quantitative (singing/voice range profile) and qualitative voice
parameters (vocal ring/singer’s formant, hoarseness/overall severity of
dysphonia, roughness/irregularity, breathiness/noise). The lingWAVES VDC
is a time-saving analysis solution that provides reliable, professional
results. Therefore, it is especially suitable to fulfill the
requirements of frequent use in everyday practice. The combination of an
integrated analysis concept with an easy application and a high
practical value is the unique key feature of this product.
Special recording technique allows
for high precision, variable measurement and display of intensity, pitch,
roughness, breathiness, overall severity, vocal ring (singer's formant) in real time. lingWAVES Phonetogram Plus follows the UEP norm
(Union of European Phoniatrics) and is certified as EU Medical Product
Class 1.
Voice Strain Test
 A basic precondition for the
choice of voice and speech professions is the suitability of an
individual for voice demands. The lingWAVES Voice Strain Test module
offers automated real-time data processing during the test run. The
test is based on recommendations formulated to standardize procedures in
the measurement of vocal load. The test parameters including required
level of vocal loading, test duration and voice intensity can be set
freely by an examiner. When the test is finished, an extensive statistic
report provides information on the patient's vocal ability.
Recording with standardized Data Sound Level Meter
Due to technical limitations, precise phonetography is not possible
with common soundcards and microphones. lingWAVES Phonetogram Plus and
Voice Diagnostic Center
requires a standardized sound level meter (SPL), a device for
frequency-weighted sound pressure level measurements displayed in dB(A).
An SPL meter is a high-quality microphone, which can be easily connected
to a PC through a free USB- or COM-port and is automatically configured by the
software. lingWAVES do not need a calibration.
System Requirements
Windows XP or Vista, min. Pentium IV,
min. 1 GB RAM, soundcard (line-in), PC-loudspeakers,
CD-ROM drive, 2 x USB-port
