Benefits / Features
Artificial Voices was distributed by our company, along with the old version of the multi-lingual speech database for telephonometry, from 1989 until the service was terminated. In spite of the termination, clients continued to send requests to NTT or our company. To meet such requests, while taking advantage of the progress of CD compatible media, our company is renewing the distribution of Artificial Voices and Conversational Speech by bundling them with the current version of the Multi-lingual speech database CD-ROMs. For clients who have purchased the 1994 version of the speech database and would like to use the Artificial Voices and Conversational Speech signals, separate sale of this item alone is available.

Artificial Voices recommended by ITU-T Rec. P.50
Application: Measurement of single channel characteristics of non-linear devices, e.g. loudspeaking telephone sets, nonlinear coders, echo-controlling devices, syllabic companders male and female voices with 10 second utterance length. The male voice is output from L-CH, and the female voice from R-CH.
Conversational Speech recommended by ITU-T Rec. P.59
Application: Measurement of bilateral characteristics of speech processing systems with speech detectors, such as loudspeaking telephones, echo control devices, digital circuit multiplication equipment (DCME), packet systems, and asynchronous transfer mode (ATM) systems.The recorded signals simulate a conversation with a male speaker on one side and female on the other. The male voice is output from the L-CH, and the female voice from the R-CH. Their conversation continues for 10 minutes.
The contents are the same as for the audio area, but all signals are individually formed as PC binary files. The sampling rate is 16 kHz.
