Most Common Procedures
- Speech & Language Sampling
- Determining eligibility
- Evaluating Rate of Speech
- Oral-Facial Examination
- Assessing _______________________
-
Speech & Language Sampling
- Job:Get a representational sample of the client’s verbal communication pattern
- Follow Language sample rules
- Use the “language” sample as a basis of looking at “speech” production in context
-
Speech Intelligibility
- A measure of the ability of a listener to understand the speech used.
- Two ways to measure
- Rating scale (see AHSA handout)
- Percent of intelligible words in a speech sample
- % =Total number of intelligible words / Total number of words spoken
-
General Intelligibility Rating
- Prosody
- 7 point intelligibility scale
- 1.Intelligible
- 2.Listener attention needed
- 3.Occasional repetition of words required
- 4.Repetitions/rephrasing necessary
- 5.Isolated words understood
- 6.Occasionally understood
- 7.Unintelligible
-
What influences Intelligibility?
- he number and type of sound errors
- Vowel errors
- Rate of speech
- Prosody errors
- The type of words that are being used
- Speech fluency
- Loudness of speech
- Inconsistent errors
- Lack of non-linguistic cues
- Level of fatigue and anxiety
-
Speech Rate Data
- Best measured in Syllables Per Minute (SPM)
- Syllables per minute
- Age 6 = 140 - 175 SPM
- Age 8 = 150 - 180 SPM
- Age 10 = 165 - 215 SPM
- Age 12 = 165 - 220 SPM
-
Evaluation for Apraxia
- speed, accuracy, sequencing of movements
- of articulators for both speech and nonspeech movements
- Oral apraxia
- -Nonspeech movements like puff out cheeks, lick lips
- Speech apraxia
- -Repetition of words with increasing complexity
