Grad F said he was writing his proposal and had finished a section on the intermediate categories he wanted to classify. He hoped to give Morgan a full rough draft by Monday, ahead of his July 25 qualifying exam. His proposed approach was to start with a reasonable set of phonetic features, use multiband classifiers for phoneme recognition, and refine the categories based on recognition errors. He planned to begin with TIMIT, then use Switchboard to study categories spanning phonemes.
