文档介绍：1960s, researcher use visualizations of pitch contours to raise learner’s awareness and enhance their understanding of intonation.
Technology
authentic samples of speech
them into a multimedia environment
Audio form
Video recording
ponents
gestures
4 main technological tools
L2 prosody instruction
Ⅰ Visualization of pitch contours
Ⅱ Multimodal tools
Ⅲ Spectrographic display
Ⅳ Vowel analysis
Visualization of pitch contours
Use:
It is used for sentence-level or discourse-level chunks of language
Limitation:
screen
How much is visible at one time and display quality is subject to sustained phonation (. vowels and nasals )
Advantage :not being language-specific
Multimodal tools
Use:
Integration of a video clip with the associate pitch contour optional annotations
Limitation
-consuming
2. not suitable for large chunks of date.
Tools: Anvil
Applicable to any language
Address the need to coordinate ponents of a speech event for analysis and feedback.
Advantage
Spectrographic display
Use:
For segmental information
Easily created by most current software program
Limitation:
Not as easily interpretable as pitch contours by non-specialists , particularly L2
learners.
Vowel analysis
Use:
Identify vowels produced by the user in relation to “ vowel space”chart
Tool: Sona-Match
by Kay
Limitation:
It can only process isolated vowels in continuous production.
Focus on individual phonemes
to the larger, contextualized speech
contrast
Methodological approaches to the use of tech. for L2 prosody teaching, two main trends can be cited
The first one: use of isolated scripted sentences in developing prosodic awareness
The second one: the use of imitation as a training technique.
typical of the “accent-reduction” work
The first one
Advantage:
1. Provides the teacher or researcher with content control
2. Allows for the focusing of learner attention.
Disadvantage:
Does not transfer as well to discourse
