FOUR OF THE MOST COMMON
Speech-to-speech (STS) systems almost entirely avoid this kind of
pronunciation error, and if it does happen, it is generally the fault
of the source speaker, not of the system. The other type of
pronunciation mistake has to do with pronouncing a sound
unclearly or substituting one sound for another.
Speech-to-speech voice conversion has a natural advantage in
prosody over TTS because it excels at duplicating the source
speaker's prosody (and the source speaker, hopefully, does
understand the text). Respeecher's technology produces far more
natural sounding prosody than TTS systems. It offers an infinite
prosodic palette for content creators.
VOCODING AND AUDIO QUALITY ISSUES
This makes intuitive sense since a high-quality waveform needs to
be sampled about 44,000 times per second, but the physical
parameters of sound change only about 100 times per second, and
the control signal that the human brain supplies to create speech
has an even lower timing precision, especially if we consider how
often we tend to change the sound we are producing.
SPEAKER IDENTITY ISSUES
At Respeecher, we are continually working to gain more control
over the aspects of speech that are possible to transfer and
convert. This helps not only with mimicking speech identity but
accent as well.
