Frequently Asked Questions
Why is the VQT program not launching?
Ensure the default directories are used during the
installation process.
Can customized speech file be used to perform measurement?
No, it cannot. The supplied collection of speech is
recommended for the ITU standard PESQ algorithm. The
collection of male and female speech is a good
representation of various phonemes in different languages.
What to do when there is an error message related to the
reference speech?
The collection of speech is only available after entering the
PESQ license. Refer to “Setting up the VQT license keys” on
page 14 for license entering process. The speech directories
may take up to five minutes before they appear in the
default location “C:\Program Files\Agilent\Telegra
VQT\Data\Wav\PESQ”, under the folders
American/British/Canton/French/German/Japanese/Korean/M
andarin/Spanish.
