Look up onThe 2HO Vowel is a tiny 2HP Eurorack speech synthesis and formant oscillator module. It mimics human vocal tones, generating everything from deep baritones to high squeaks. It features two unique algorithms (Speech and FOF Synthesis) and manual or CV control over frequency, vowels, and formants. Some slight rack rash action on the 2HP label at the bottom of the module. Fun little module!
