Chapter 16

Spectrograms Homework Analysis
I want two to three pages each day (fri-mon-tues-wed). OK?
Your Spectrogram homework will be worth 30 points.
Analyze of your voice.
Singing Voice compared to talking voice
Talk in a noise filled room---investigate which frequencies are affected.
Determine which frequencies are the strongest.
Talk in a soft voice and a loud voice. Determine which frequencies are affected.
Depiction of Phonemes
Sonorants - Speech sounds which are characterized mainly by voicing, the repetitive opening and closing of the vocal cords, comprise a majority of all speech sounds, 25 of the 41 phonemes in a minimal set .
Fricatives - Friction sounds, 9 of the 41 phonemes.
Plosives - Explosion sounds (including affricates), 8 of the 41 phonemes .
Silence - Phrase marker, breathing, and even mini-silences which are phonemic, the closures before a plosive.
Think up an Experiment that will demonstrate your knowledge
of the Spectrogram software.
Summarize what you learned by using this software.

Spectrogram Analysis is your Homework the rest of the semester.

Quiz on Chapter 30 on Friday, May 3, 2002
You will be asked to answer all the questions.

1) Why is noise so hard to quantify? (see section 30.2)
2) What affects sound propagation outdoors? Why? (see section 30.3)
3) What are possible noise sources in machines and how can we reduce the noise?
4) What are the noise sources created by automobiles? The solutions?
5) According to the investigations of Cohen and colleagues (Cohen, et al., 1981),
reading and math scores of third grade students in noise abated classrooms were
higher than those in noisier (thank you, Theresa) classrooms Why?

Quiz on Chapter 31 on Wednesday, May 8, 2002
You will be asked to answer all the questions.

1) Where is the primary site of ear damage due to noise? What happens? (see section 31.3)
2) What are speech cues? How does noise affect a listener's cues?
3) What are Objective and Subjective tinnitus? What are two forms of Sensorineural Hearing loss? Explain.
4) What Are the Common Problems of Hearing Protectors? (Scroll down)
5) The hearing system is divided into two subsystems which respond to the two modes of speech.
The low frequency subsystem identifies pitch and the characteristic resonances of the person speaking (vowels, chest and head tones), and the high frequency subsystem identifies stops and starts.
The brain integrates and interprets both modes to form an image of words.
How does noise affect these subsystems?

Survey III - 3 parts
a one-month odyssey worth 100 points

Part I - 3 Quizzes
On these Wednesdays, in class, you will be asked to give short answers
to 3 of the 5 questions on the Chapter 15, 16, 30 and 31 pages.


Part II - The Physics of Speech

Concept Map (25 pts.)
Vocal Organs, Larynx, Vocal Tract , Formants, Phonemes, Speech Recognition,
Noise, Hearing Loss, Ear Damage

Part III - The Physics of Speech (PPP)

Project + PowerPoint Slide Presentation (100+50 pts.)
This part can be included as part of your Project.
In other words, I want you to combine the Power Powerpoint Presentation with your Project.
10-20 slides with uumph!
Vocal Organs, Larynx, Vocal Tract , Formants, Phonemes, Speech Recognition,
Noise, Hearing Loss, Ear Damage

or
Conventional Test (75 pts.)


Remember: to demonstrate the physics of Speech with diagrams and equations, not just words!
This is something that you will want to keep and refer to once in awhile!

Example: My Big Bang Diagram?

Any student wishing to drop their lowest test grade will need to take the Final.
Any student who has an A---will not have to take the Final.
Any student satisfied with their grade---can keep that grade and not take the Final.
