If, rather than have your recordings generated automatically with Text to Speech (TTS), you would rather record your own samples, you will need to ensure that the resulting files are in a format we can use. You go through the guide below or simply look at the screenshots album.

Plan your call flow in detail, then send us the script or flowchart and recordings and we will make it happen. The recording files must be a Windows WAV sound file (extension .wav). The format is PCM 8kHz 16 bits Mono. If it is not in the proper format, we will attempt to convert your .wav file, but success is not guaranteed. We recommend using a program such as the free, multi-platform Audacity, also portable, to make the recording.

Audacity Preferences for IVR recording

In this application, you can easily set the Project Rate to 8000 Hz in the lower left corner. 

Audacity Preferences Box

To set the default sample rate to 8000 Hz and the default sample format to 16-bit, before starting to record, go to Edit -> Preferences -> Quality.

Waveform Audio Track menu: Set Sample Format
If you have started the recording already, click the down arrow in the top right corner of the wave form.

Once you are done with your recording, you can further modify, clean up or apply effects to it.

Save your file, previously set to 8kHz, as a 16-bit WAV PCM

When you are satisfied, go to File -> Export and choose the .wav Microsoft PCM 16 format, then give it a name and click Save, and make note where it is so that you can find it later.

Alternatively, you can send us via our form the text of the messages together with the flow chart and we will optionally convert it in a computer voice, male or female.

Use of a professional voice announcer is a premium service that can be quite expensive, depending on the size of the project and the languages requested.

If you want to use your own recordings but do not have access to a computer and would still rather not pay for voice talent, you might be able to record on your smartphone. In the Android app market, you can use:
  1. Smart Voice Recorder (81695 users, 4.7) - allows changing the sampling rate which directly affects quality. Unfortunately, we can only use PCM 8kHz 16 bits Mono.
  2. Easy Voice Recorder (27022 users, 4.5) - allows recording to PCM as well as other formats
Keep in mind that for the recordings to be useful, the final waveform should be "clean" and sufficiently "loud", meaning no significant background noise, or a good signal to noise ratio. For the most part, though they may sound robotic, computer generated voices tend to be "cleaner" than human recorded messages.

This service is free of charge, subject to the aforementioned condition, if you provide us with the flow chart and the recordings in the proper format and use our form. Otherwise, we will provide you with an estimate based on your instructions. You may send us your recording(s) by uploading to Box, Dropbox, Google Drive or SkyDrive, then sharing it with the email admin at EZvoip.co
