Careful using this with apraxics – SmallTalk Consonant Blends Review

Nice videos, clear audio. My only complaint is that some of the demos model unvoiced consonants with an added voiced vowel. "ST" is pronounced S -T- UH. For clients with difficulty in confusing voiced and unvoiced sounds, this might be misleading.
