LAB 5: Sound Generation at the Larynx: Characteristics of the Glottal Source

Labs: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17

The main purpose of this laboratory is to observe glottal-source variations using analysis of vowel spectra.

Here are the resources you will need:

Lab 5 Handout (PDF)

Utterances

• You will analyze a set of pre-recorded example utterances that are stored in the labc account.
• You will record some new utterances during the lab.

If you do not have access to the labc account, or if you do not have access to the tools for recording the new utterances, you can download the utterances for this lab.

The Tools

• record - the recording software (VAX)
• xkl - used for spectrum and waveform analysis (UNIX®/Linux®)
