Spectrogram v4.1.2 is a dual channel audio spectrum analyzer for
Windows 95 which can provide either a scrolling time-frequency
display or a spectrum analyzer scope display in real time for
any sound source connected to your sound card.
Spectrogram requires Windows 95, at least 16 mbytes of RAM, and
a Windows compatible sound card. Spectrogram is freeware.
Voice Onset Time (VOT)(onset time is time from release from closure to voicing
bat /b/ voiced stop
pat /p/ voiceless stop
CV syllables (consonant-vowel)
VOTs < 30 milliseconds perceived as voiced
VOTs > 30 milliseconds perceived as voiceless
labials ahve 0-30 msec VOTs, velars (/g/ /k/) have 30-150 msec VOTs
drawing of overlapping normal curves illustrating possible Von and Voff detectors, where continuous stimulation by (for example) /b/ will fatigue the Von detector and shift the boundary so Voff is relatively stronger
experiments by Warren. "The state governors met with their respective legislatures convening in the capital city." Replace first /s/ in legislatures and replace it with a cough yields phonemic restoration
"The #eel was on the {table, car}." If # is cough (or other noise), then phonemic restoration is dependent upon the terminal word. Perception isn't phoneme by phoneme, then.
Problems with PS (finite state grammars):
missing elements: Stop! v. Otto stop it!
ambiguity (structure, phonetic, lexical, or PS)
identical form yet different (Noam is easy to please v. Noam is eager to please; Noam is object, subject respectively)
different form by same meaning (Everyone in the room knows 2 languages v. Two languages are known by everyone in the room)
discontiguous elements (The girl that Bill met lives here. middle 3 words separate elements)

Self-test Questions
Is it possible to point to any particular word and identify it as the
longest word in the English language? Explain.
Draw a phrase structure tree for "George stayed after school
with the teacher." Now extend the tree one level further by showing the
morphemes that compose each word (where there is more than one in a single
word). Should this tree diagram be considered as one kind of knowledge
or two (syntactic and morphemic)? Explain.
Test your understanding of relative clause formation by determining
the main and subordinate sentences in the Ambiguity Example sentence 1b.
Describe the structural ambiguity of the sentence, "The princess thought
the shooting of the prince was terrible." If possible, illustrate your
answer with tree diagrams.
