25
reproduce amplifier of record player
allows information coming from tape to be amplified
26
speaker of record player
changes electrical energy to acoustic energy
27
tape of record player
composed of oxide particles, which can be magnetized and are glued to the clear plastic tape
28
considerations to remember during recording
microphone placement, phonetically balanced material, recording procedures (tape speed), playback procedures (background sound)
29
tape speeds
fast speed= high quality slow= conserves the tape
30
15/16 ips
long duration recordings
31
1 7/8 ips
used for long duration speech recordings slowest domestic tape speed
32
3 3/4 ips
most common speed fairly good quality for speech recordings and off air radio
33
7 1/2 ips
highest domestic speed and slowest professional speed used for advertisements
34
mono input channel
one channel
35
stereo input channel
both channels
36
VU meter
volume control meter that lets you know if a signal is not strong enough or too strong
37
playback procedures
listening for background noise that will interrupt recording
38
VisiPitch
electronic device used for speech analysis and providing feedback to clientss
39
VisiPitch signal is captured by
analog-digital board which stores signal digitally which can be manipulated and analyzed easier than analog signals
40
VisiPitch programs
6 programs Pitch and Energy trace Pitch and Energy games Sibilant/Vowel training Voice quality assessment Waveform editor Delayed Auditory feedback
41
Pitch and Energy trace
realtime display of VFF and displays a trace of signal intensity uses two screens, one with model the client is attempting to match teaches intonation patterns and pitch controls
42
Pitch and Energy games
visual games controlled by pitch and intensity targeting: voicing of sound- turtle loudness control- giraffe pitch control- mouse and cheese sustaining voice- leapfrog
43
Sibilant/Vowel training
analyzes for wave composition input is analyzed to match frequency formant closest to vowel
44
Voice Quality assessment
analyzes sustained vowels for voice characteristics of jitter, shimmer percent, noise to harmonic ratio, and voice turbulence index used to compare pre/post therapy samples
45
waveform editor
graphically presents waveform of acoustic signals which can stored and edited (similar to oscilloscope, but can be stored, modified, played back, and analyzed best used with adults
46
delayed auditory feedback
records a signal and reproduces the signal after a brief interval (10-500 milliseconds) effective with disfluency
47
Computerized Speech Laboratory
primarily a research tool signals are captured, analyzed, stored, and edited
48
Features of Computerized Speech Lab
LPC frequency response FFT power spectrum Spectrogram LPC formant history pitch, loudness, intensity analysis
49
LPC frequency response
uses linear predictive coding to analyze and display wave composition useful for determining vowel formants
50
FFT power spectrum
analyzes/displays wave composition using Fast Fourier Transform- more discrete than LPC useful for determining harmonic integrity; clear peak, good integrity
51
spectrogram
spectrographic display of wave composition can be manipulated by sampling rate, display, change of bandwidth procedure
52
LPC formant history
uses LPC method to find and display formant (more complex and not a real time display)
53
Multidimensional Voice Profile
component of CSL and allows voice samples to be acquired, stored, and analyzed
54
components of Multidimensional voice profile
33 parameters can be measured and displayed from one sample and charted as inside or outside of green circle (out=pathological) "norms" are compared to sample and measures treatment efficacy (jitter below 2.0/shimmer below 5.0)
55
Multidimensional Voice Profile objective evaluation
important counterpart to perecptual
56
Multidimensional Voice Profile perceptual evaluation
labels "breathy". "harsh" etc
57
Speech viewer
contains different games and charting software for evaluations and treatment for pitch, loudness, voicing and sound production signal is digitally captured and displayed addresses awarenesses, skill building, and patterning
58
sound presence awareness
enhance awareness of sounds of phonemes (4 games)
59
loudness range awareness
enhance awareness of loudness and changing of intensity
60
voice presence awareness
awareness of whether a sound is voiced or not
61
voice onset awareness
awareness of voicing onset and control over voicing
62
voice timing awareness
improves coordination of respiration and voicing
63
pitch range awareness
awareness of vocal pitch and quantities pitch range
64
pitch control skill building
builds skill in voluntary fine control of pitch
65
phoneme accuracy skill building
improve accuracy of phoneme production 23 sounds, sustained phonemes, and speech segments
66
multi-phoneme chain skill building
develop skills in producing sequence
67
two phoneme and four phoneme contrasting skill building
improve accuracy in differentiating
68
pitch and loudness patterning
increase skill in producing speech patterns
69
spectra patterning
use spectral analysis to improve accuracy of phoneme production; has visual reinforcements targets: pitch, prosody, voicing, phonology
70
nasometer
measures oral and nasal airflow separately and calculates ration between the two measures
71
how nasometer works
two microphones on vertical plate in face mask with a horizontal plate separating nasal and oral cavities patient then reads passages with different nasal "norms" to compare
72
nasalance score
how much nasality is in a speech sample
73
hypernasality
high
74
hyponasality
low
75
nasal section of nasometer passage
60%
76
rainbow passage of nasometer passage
35%
77
zoo section of nasometer passage
15-20% has no nasals, but low score as a result of breathing
