LAB 8: Prosody: Acoustic Evidence for Prosodic Constituent Structure

The main purpose of this laboratory is to analyse acoustic evidence for phrase boundaries. You will use utterances spoken in one of two prosodic forms: AB utterances and BC utterances. (See the handout for details.)

Here are the resources that you will need:

Utterances

You will use a set of pre-recorded utterances that are stored in the labc account in .wav, .f0, and .sd formats. These utterances are:

• AB utterances (2 each for four speakers).
• BC utterances (2 each for four speakers).

If you do not have access to the labc account, you can download the utterances for this lab.

The Tools

You can use either one of the following two analysis tools:

• xwaves - used for spectrum and waveform analysis (UNIX®/Linux®). If you use this tool, you also have the option of using the transcriber script. This script configures xwaves for the types of tasks done in this lab.
• xkl - used for spectrum and waveform analysis (UNIX®/Linux®)
