I did some audio recording today. It’s always strange to hear your own voice how others hear it, played back. Other technologies, in particular writing, create external representations of our thoughts and persons, but none is so intimate, so eerily similar yet different from our internal perceptions, as audio. After listening to the playback for a while, I can’t even hear my own voice, not really, and even the meaning of my words grows fuzzy, until all I can make out is the tangle of interwoven tones and intonations, all sound and no substance.
