LINB09H3 Lecture Notes - Lecture 6: Speech Recognition, Acoustic Phonetics, Sound
Document Summary
Thus far in the course we have described sounds in terms of: their articulation within the vocal tract the way they can be transcribed in the ipa. We can also describe sounds in terms of their physical (acoustic) properties. The way we hear sounds depends in large part on their amplitude and resonant frequencies. Being able to describe and analyze the acoustics of speech is useful. Gain insight into human perception and sound recognition. Vowels can be more easily characterized acoustically than articulatorily. Data collection: audio recordings are much easier to collect than articulatory recordings. Crucial for automated speech recognition (asr) and speech synthesis. When you say something the air molecule presses against each these peek rarefaction and fluctuation. Why some sounds are confusable look at human perceptions categorize vowels better than by ear. When you say things, you are causing pressure in the ear (not on exam)
