IVR Sound Library

The IVR sound library allows you to manage and handle your IVR sounds, replace the default IVR prompts and recordings, and create customized IVR sound sets, for example, for language variants.

To Upload IVR Sounds

1. From the VCC Live menu, select Contact Center > Global Settings.
2. Select the IVR sound library tab.
3. Press Add to create a new folder. This will create a set that contains the default IVR sounds.
4. Enter a name for your folder. Supported characters: alphanumerics (a-z, 0-9) and underscore (_) characters.
5. Choose a language for your set.

   Now you need to download the default sound file set, so you can replace the default sound files with your own sound files.

6. Select the folder you’ve just created, then press .
7. Navigate to the folder you want to save the sound files in. The sound file set comes in ZIP format, which you will need to decompress.
8. Now you can start replacing the sound files in this folder. Make sure the filename and the format of the sound file you want to upload match that of the default sound files.
9. Once you’re finished replacing the files you need, recompress the folder.
10. On the IVR sound library worksheet, press .
11. Browse to your sound file folder, and upload the folder.

Create IVR Prompts Using Text-to-Speech

Our Text-to-Speech feature can convert any text into spoken words and generate a WAV audio file. This will allow you to create phone greetings and IVR prompts that you can use in your projects.

Note: The Text-To-Speech feature relies on an advanced voice synthesizer system to generate human-like speech in high-fidelity audio format.

To Generate Audio Files

1. Select a project from the project list, then select Channels > Voice > Inbound.
2. On the Text to speech tab, enter the text you want to convert into speech in the Text input field. Make sure the text is no longer than 1000 characters.
3. Select a language and gender.
4. Press Download, then save the audio file to a folder.

To Modify the Speed of Playback

If you find the playback speed of your generated IVR sounds too fast or slow, you can adjust them using custom parameters by the Speech Synthesis Markup Language (SSML). VCC Live supports Text-to-Speech engines by both Google and Microsoft Azure. Here is how you can use them:

Google

1. Select a project from the project list, then select Channels > Voice > Inbound.
2. On the Text to speech tab, enter the following expression right in the Text input field, which creates a sound file where the words are spoken slower:

   <speak>
   <prosody rate="slow" pitch="-1st">Lorem ipsum dolor sit amet</prosody>
   </speak>
   

3. Replace the placeholder ‘Lorem ipsum dolor sit amet’ text with your text. Make sure the text is no longer than 1000 characters.
4. Select a language and gender.
5. Press Download, then save the audio file to a folder.

Tip: Several other handy commands are available for Google’s SSML feature, such as spelling (the ‘verbatim’ parameter) or pauses (the ‘break’ parameter).

For more information and a list of available parameters, please visit Google’s SSML reference page.

Microsoft Azure

1. Select a project from the project list, then select Channels > Voice > Inbound.
2. On the Text to speech tab, enter the following expression right in the Text input field, which creates a sound file where the style is cheerful:

   <speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis" xmlns:mstts="https://www.w3.org/2001/mstts" xml:lang="en-US">
    <voice name="en-US-AvaMultilingualNeural">
      <mstts:express-as style="cheerful" styledegree="2">
        Hello I'm so happy today!
      </mstts:express-as>
    </voice>
   </speak>
