A. Weill–Duflos, P. Fortin, F. Al Taha, J. R. Cooperstock


Context

  • Voice characteristics influence perception of speaker’s professional abilities

  • Voice pitch is one of the factor

Can we influence it with vibrotactile feedback ?

Setup

  • Chair with 100W tactile loudspeaker
  • TTS voices from Google Wavenet models

Experiment

I urge you to vote for me this November

  • pair of voices
- chose the “competent”/“stronger”/“trustworthy” - low/high pitch with/without haptic M/F

Results

Choice of high-pitched voices:

Conclusion

  • did not replicate previous findings
- strength is reinforced

Thank you!
