In order to identify words with sound, I think we use certain aspects of the sound, not all aspect of sound. For example, I think that we can identify words if timbres (units of timbres) and pitch relation between these timbres are identified on the condition that the timbres appear with same weights, and we don't need loudness and duration to identify words. How about in English? What aspect of sound do you need to identify English words?
