Intelligibility of Different Synthesized Mandarin Speech by Cochlear Implant Listeners
To investigate the intelligibility of synthesized Mandarin speech by cochlear implant patients and analyze the influencing factors.
Methods
2
17 Mandarin-speaking cochlear implant users participated in the test. All the sentences were naturally produced by a single female talker in slow clear speaking style (F-Nat) or were synthesized using the iFlyTek TTS engine.Five synthesized voices (F-Slow
F-Normal
M-Normal
F-Emotion and B-Accent)were selected to represent different talker genders
speaking rates
and speaking styles
speech recognition scores were analyzed.
Results
2
For CI users
the worst speech recognition scores were with the B-accent sentence.There was a significant effect of speech type [F(5
80)=53.8
P
<
0.001
]
. Post-hoc Bonferroni pair-wise comparisons showed that performance was significantly better with F-Nat than with any of the synthesized voices
significantly better with F-Norm than with F-Emot
or B-Acc
significantly better with F-Norm than with F-Emot or B-Acc
significantly better with M-Norm than with B-Acc or F-Emot
and significantly better with F-Emot than with B-Acc (
P
<
0.05). There was no significant difference between F-Slow and F-Normal(
P
=0.97)
so was F-Normal and M-Normal. There were no significant correlations among any of the demographic variables and speech types (
P
>
0.05).
Conclusions
2
CI users were susceptible to dynamic changes in speech
