The effect of formant trajectories and phoneme durations on vowel intelligibility

We examined how much listeners can benefit from listening to ldquoclearrdquo (CLR) speech compared to ldquoconversationalrdquo (CNV) speech, both spoken at different speaking rates.

Results showed only tense vowels of CLR speech had a significant difference between CNV and CLR...
