Subject: Creating Phonetic Stimuli - F1/F2 Vowel Continuum

 
I am a PhD candidate at the University of Michigan who is currently creating
stimuli for a speech perception experiment.

My original plans were to use source-filter vowel resynthesis on actual tokens
spoken by a human; however, I have not been able, using Praat, to create
natural sounding stimuli when the formant values are changed drastically -
600Hz + in either direction. I am aiming to create a 13 step continuum, from
around 200Hz to 900Hz on F1 and from 1100Hz to 2100Hz on F2 (with Hz changes
on both formants in each step; going from /i/ to /u/ (as in PUTT, CUT; the
''wedge'').

I am looking to speak with someone who:

1) Either has experience in creating natural sounding stimuli with such large
Hz changes and would be willing to collaborate with me on stimuli creation
2) Has experience with Klatt synthesis and would be willing to collaborate on
synthetic stimuli creation
3) Has experience with any other speech synthesis and would collaborate.

I can compensate for someone who would be a research assistant/consultant and
help me with this.

Thank you
