Speech Audio Characteristics
Audio can be encoded at different sampling rates (i.e. samples per second – the most common being: 8, 16, 32, 44.1, 48, and 96 kHz), and different bits per sample (the most common being: 8-bits, 16-bits or 32-bits). Speech recognition engines work best if the acoustic model they use was trained with speech audio which was recorded at the same sampling rate/bits per sample as the speech being recognized.

Famous quotes containing the word speech:
“There is the old brute, too, the savage, the hairy man who dabbles his fingers in ropes of entrails; and gobbles and belches; whose speech is guttural, visceral—well, he is here. He squats in me.”
—Virginia Woolf (1882–1941)
