The Linguistic Data Consortium at UPenn https://www.ldc.upenn.edu/ has a huge inventory of speech databases. I think the Articulation Index (catalog number LCD2005S22 and ISBN 1-58563-346-1) provides material that would meet both of your aims. It has 20 speakers with a set of approximately 2000 syllables in common to all speakers and approximately 20 unique syllables spoken by only a single speaker. The syllables were spoken both in the middle of a carrier phrase and in “isolation” (i.e., after a short pause at the end of the carrier phrase). The recordings were manually segmented to isolate the target syllable. There is also approximately 10 minute of conversational speech for each talker.

Subject: [AUDITORY] Phoneme database
Dear list,
I am looking for a phoneme database to train a supervised machine learning method for ASR. There is the well-known TIMIT database, which contains the phoneme labels for each recording, but an isolated phoneme database would be much better for me. I also found some websites mentioning the Oxford Acoustic Phonetic Database or the University of South Florida Audiovisual Phone Database, but no clue about how to find the databases themselves. Any help would be highly appreciated.
Best Regards
Kamil Adiloglu
