Hello

Making the best possible recordings

There are many factors to consider when recording alternative voice prompts in order to get the best

results. Below is a summary of the points to bear in mind.

Recording format

It is best to make each recording with the ideal settings and hence avoid any sample-rate or resolution

changes. As discussed, the ideal format is Microsoft Wave (.WAV) format, uncompressed, mono, at

16 kHz and 16-bit resolution.

If you are unable to make mono recordings, the ISDN Gateway can convert stereo recordings.

Background noise

It is important to minimize background noise (hiss) as much as possible. This includes ambient noises

such as road noise and slamming doors etc. but also try to keep fan noise and similar to a minimum.

When played back by the ISDN Gateway, samples with background noise are very apparent.

Consistency

If possible, record all voice prompts in one session. This will ensure that all voice and background

conditions remain constant and the recorded voice will sound similar from prompt to prompt.

Volume

Record prompts using a relatively constant loudness of voice. Although it may take some trial and

error, the best recordings will result from speaking loud enough that the voice is recorded loudly

compared to any residual background noise, but not so loudly that it sounds distorted when played

back.
