Instruction to Alter Pitch Level
Instruction for lowering a student's pitch level and regulating the pitch range can be supported by the use of the voice meter on the Speech Viewer III The meter and the available statistics provide valuable information on pitch level and pitch range.
Student tries to monitor level in conversation.
In addition to setting a target line (using the CSL Real-Time Pitch) for the preferred average pitch level, it is helpful to ask the student to judge the productions they have just spoken and seen. Here the student sees that her pitch is well above the 250Hz target line and indicates that she feels she has not practiced enough recently to achieve the lower, more appropriate pitch on the functional words she has brought to class.
With the visual feedback students often make several attempts until they are satisfied with their productions. Here we see production of doll, call, hard with self-corrections based on a line showing real-time pitch compared to a target pitch line.
Even while practicing control and self-monitoring pitch, it is important to encourage students to maintain the best articulation possible. Here the student is reminded that /sh/ and /t/ are voiceless and /m/ is nasal.
Sometimes it is necessary to go back and forth from one program to another when using instrumentation. Here the student was primarily working on pitch. The instructor switched to the Real-Time Spectrogram to demonstrate some of the articulatory features of the word "hot." When the student asked about her pitch, the instructor switched back to the original program, the CSL Real-Time Pitch.
Instruction to Improve Prosody
Visual feedback helps student control pitch and loudness.
A student can use an instructor's model, his imitation, and statistical information to facilitate alterations in intonation.
