Media player software, such as QuickTime® Player, RealOne™ Player, or Windows Media® Player, is required to run the .wav files in this section. RealOne™ Player software is required to run the .ram files in this section. MATLAB® software is required to view and run the .mat files in this section. File decompression software, such as Winzip® or StuffIt®, is required to open the .tar and .zip files in this section.
This page contains digitized media files for use in the labs. Most of the files are audio data, but there are also image files and other types of data. For some of the labs, you are asked to record your own voice. If you do not have the tools for making such recordings, example utterances are provided as spoken by both a female speaker and a male speaker. The audio files are given below under the heading of the relevant lab.

In Lab 1, you will record a database of speech utterances for use throughout the semester. Below are links to sample databases recorded by two speakers, one female (HH) and one male (KS).
Note that although these files have a .wav suffix, they are in Klatt format, for use with the Klatt speech-analysis tools (xkl); they are NOT Microsoft .wav format. (If there is a desire to use these files with analysis tools that require MS .wav format, we may consider providing both formats in the future.)
You can download tar archives of an entire database here:
female sample database (TAR - 4 MB)
male sample database (TAR - 4 MB)

You will use the spontaneous speech recorded during Lab 1.
If you do not have your own recordings, you can download speech samples that contain clear renditions of several words along with renditions of the same words as produced with reduced segments. The tar file will contain samples from the same male and female speakers (KS and HH) that recorded the speech samples for Lab 1.
Download the Lab 7 examples (xkl format) here. (TAR)

You will use the following utterances, produced by four speakers and stored in the labc account:
- Part A: Please say Maine or Duke and Rice will play.
- Part B: Please say Thomas or Kenneth and Lucas will stay.
Each sentence was produced with two different prosodic forms, and each prosodic form was produced twice by each speaker, for a total of 32 utterances. The utterances are available in two formats, Xwaves (.sd and .f0 files) and Xkl (Klatt .wav files).
Download a tar/zip archive of the utterances required for this lab (TAR - 12 MB).

You will use either the utterances for Part A or the utterances for Part B:
- Part A:
1) Utterances 3-10 in files lcorn.16k (Xwaves format), located in the labc account (Download files lcorn.16k (LCORN) and lcorn.f0 (LCORN) here)
2) Utterances from Lab 8, Part A
- Part B:
The following words, recorded by two speakers: "fat", "fad", "fade", "cup", "cub", "coop", "pick", "pig", "peak", "men", "main', "mate", "tuck", "tug", "take". These files are in two formats, Xwaves (.sd files) and Xkl (Klatt .wav). (Download a tar/zip archive of the utterances here (TAR - 15 MB).)

In this lab, you will participate as a subject in two types of intelligibility tests. If you attend the lab, you will hear the stimuli on audiotape. If you do not attend class, you can download audio files of the tests below. In order to take run the tests on your own, you will need to download the response and answers sheets from the Lab 10 page.
- Consonant-vowel (CV) nonsense syllables: 10 dB SNR (RAM) | 5 dB SNR (RAM) | 0 dB SNR (RAM)
- Sentences in noise (Spin test): Introduction (RAM) | Practice Items (RAM) | 0db SBR (RAM) | 10db SBR (RAM)
A third type of test is available, although it is not presented in class. You will need to download the response and answers sheets from the Lab 10 page.
- Consonant-vowel-consonant (CVC) nonsense syllables: 0 db SNR (RAM)

In this lab you will use .gif files of cineradiographic images. Because the full database of these images is rather large, it will only be available to students attending the lab. Sample .gif files can be downloaded here:
Download file KNS_6400995.gif (GIF), /a/ in "he'tat"
Download file KNS_6401423.gif (GIF), /a/ in "soggy"
Download file KNS_6400919.gif (GIF), /u/ in "he'tu"
Download file KNS_6401621.gif (GIF), /u/ in "shoes"

For this lab, students will record new utterances. If you are unable to record new data, you can use the sample utterances provided for Lab 5, part B (either "pat" or "bad").

In this lab, you will use data recorded by an x-ray microbeam system. There are data for two speakers and they are in MATLAB format (.mat files):
Microbeam data for speaker JW16 (ZIP - 1.7 MB) (The ZIP file contains four .mat files)
Microbeam data for speaker JW18 (ZIP - 1.8 MB) (The ZIP file contains four .mat files)
