Recording system prompts professionally
If you choose to obtain professional recordings, you should first choose a voice vendor with
experience in telephony recording. Then:
• Select a voice.
• Provide the appropriate Wave files to the vendor in formats they can use.
• Test the new prompts for voice quality, usability, file-naming accuracy, and indexing
accuracy.
• Deploy the new prompts.
Selecting a voice
The vendor will often provide you with 44kHz, full-bandwidth voice samples from which to
choose. Ask your vendor to provide voice samples that have been re-sampled or recorded as
MuLaw PCM Mono 8 kHz, which is the format used in Wave. This will ensure that your
selection is based on how the voice will actually sound when used in your Wave system.
Keep in mind that high-pitched voices and high-frequency sounds degrade more as a result of
this type of re-sampling, which may result in considerable change in higher frequency sounds
at telephony bandwidth.
