77. Recognizing speech--top down

Whenever we hear sound that bears information, we instinctively attempt to decode it. If it is speech, we simply cannot ignore it unless it is deemed gibberish. Here, knowing how to do it is critical. It includes acquiring numerous language templates in the form of auditory image and applying them ...

76. Recognizing speech--bottom up

Someone speaks; we listen. How is the acoustic waveform transformed into a meaning of spoken message? As the speech signal travels from the cochlea to the auditory cortex, the level of information abstraction deepens. Spectral analyses, the very first information processing occurring at the inner e...

74. How it's made: your voice

It begins with the vibration of the glottis, a small slit-like structure in the larynx. Miniscule air bursts from the glottis travel through a tube called the vocal tract, are filtered according to the resonance characteristics of the tube, and become like a human voice. Specific speech sounds are ...

73. Piano tuners must have a great sense of pitch, right?

Well, that's only the beginning. Their task actually centers around hearing for beats--that warbling or wowow-yoyoe-ing interactions of two waveforms with slightly different frequencies {episode 30}--and counting them. This is because the equal temperament scale produces slightly off-integer ratios...

71. No Tower of Babel for music

Do-re-mi-fa-sol-la-ti: the 7-note scale in the most common Western music. Kung-saang-kaak-chee-woo: the 5-note scale in traditional Korean music. What are their pitches? It sounds like do-re-mi-sol-la, but is it valid to use the Western do-re-mi scale here? Back then, Koreans must have set those no...

68. Pythagoras, the world's first acoustician

Pythagoras discovered that, the frequency ratios with small integers, e.g., 1:2 or 2:3, made pleasant sound. That was the first scientific account of what we call "harmony" in history. Today's physics explains this well. Virtually all tones are made up with many modes of vibration, producing harmon...

66. Pseudo-absolute pitch: not so a flashy word

Often we have a singer begining a song with his own key, then the accompanist joins in with the right key. If absolute pitch holders are so rare, why do we see so many of those talented accompanists? Most of them have pseudo-absolute pitch, the skill acquired through extensive musical training. Tho...

65. Absolute pitch--flashy

The ability to name the musical note upon hearing a tone, or vocalizing a pitch of a given note without a reference, is revered as a marvel. Wonder stories spread easily: once you hear it you willingly propagate it to others, or you originate one yourself: "My kid has perfect pitch!" In reality, we...

64. Voice pitch, musical pitch

Pitch has such a multi-faceted impact on hearing that one's utterance of the same message can lead to a hug or fistfight, depending on very small variations of voice pitch, or the fundamental frequency of the voice. When you do an impression of someone, you primarily copy the intonation, or pitch v...

63. Flexibility of musical pitch

Hum along a melody played by an instrument. The actual fundamental frequencies, what we call pitch {episode 11} generated by the instrument may be way over or under your vocal range. Most of the time, we conveniently shift the octave range up or down, i.e., the frequencies are doubled or halved fro...
