What audio prompts or files do I need for the IVR phone apps?

This articles gives you some practical and technical tips to make the best out of your audio prompts. If you want to find out more about uploading prompts to babelforce Manager App feel free to read this article.

To achieve the best possible audio quality you should record your prompts/announcement in WAV file format. Almost any WAV PCM linear audio file format is supported from our platform.

If you do WAV PCM linear at 16bit and 44kHz, then you'll get a good result and have good quality files that you can re-edit, etc. Telephone lines will only use max 8kHz anyway, so we will down sample for you. You can also use mp3 compressed audio files.

Any other compressed format will NOT work.

It is a good idea to prepare a prompt/audio recording sheet. Usually they look something like this if you are doing one language: 

They should be prepared for what any voice talent or studio will expect to work from. It specifies a filename, prompt wording and there are notes for the voice talent where you need to indicate how you wanted the voicing.

It is a good idea to give your prompt descriptive filenames that have a consistent naming convention, where the type or purpose is visible at the beginning of the filename.

Also if you are recording multiple languages or brand variants, then it is good to use a recording sheet like the following, with prefixes for the language and brand labels. So for example, the first prompt in the table, will end up having different variants for each language:



 If you have brand variants instead of languages, then it is good to label the filenames as follows:



Or if you have both languages and brands, then you will have something like this:






Note, filenaming is up to you, these are just suggestions to make audio file management, selection, etc. easier. You can of course name a file whatever way you wish and it will work.


Have fun creating great dialogues!
