Question 14/XII - Application for the artificial voice
(New Question)

Considering

(a) that the progress of the last study period concerning the artificial
voice generation, which has been included in the new Recommendation
P.50;

(b) that the results of the international data collection of speech
samples;

(c) that the probability of applications of Recommendation P.50 to
objective speech quality evaluation for new digital technologies, i.e.,
objective evaluation of low bit rate coders, DCME, echo control devices
and loud-speaking telephones, are urgently required.

Administrations are requested to contribute on the following subjects:

1. Where can the newly standardized artificial voice be applied for the
objective evaluation of telecommunication equipment. What are the
limitations in any given applications?

2. Which characteristics of real speech are still missing?

3. How can silent periods be inserted into the artificial voice to
simulate actual conversation?

4. How can the artificial voice be applied to the calibration of the
digital speech voltmeter?

5. Does the application of the artificial voice as provisionally
recommended in P.50 have any influence on the conventional load defined
in Recommendation G.227? If yes, what modification is necessary in the
text of that Recommendation?
