Why Speech Analysis?

• Established layer in recognition, synthesis and coding
• Model estimation: needed low dimensional vectors
• Psychoacoustic results - don't need full waveform
• Analysis for analysis sake - learning about speech
• Linguistics
• Pathology

For example, to make sense of speech waveforms such as figure 1 - or zooming in, figure 2, which are the waveforms for the words ``She had your dark''.

  
Figure 1: The waveform of an utterance ``She had your dark''

  
Figure 2: The waveform of an utterance ``She''
