Our Voices on Cell Phone

Have you misunderstood someone's voice on your cell phone?

Actually, it's a natural thing.

The voice which you have heard is a kind of synthesized voice.

Around three thousand voices are registered on the codebook, and the most similar voice is chosen based on the characteristic of speaker's voice and played while we are talking.

Since our voice data are too enormous, this technology called "CELP" has been used.

Therefore, if there are two persons who have a similar voice, it will be so difficult to distinguish them in dependence upon their voices.

• Therefore, if there are two persons who have a similar voice, it will be so difficult to distinguish them in dependence upon their voices.
• Therefore, if there are two persons/people who have a similar voice, it will be so difficult to distinguish them in dependence upon their voices.

  "Persons" is not incorrect but "people" is most commonly used.
