Manage your audio files in the centralized announcement repository, including those generated using Text-to-Speech (TTS), allowing you to use them across services like auto attendant, music on hold, and call queue announcements.

Set up a common repository, which allows different locations to use a shared announcement. Services such as Auto attendants, Call Queues, or Music On Hold can point to a common announcement in the repository.

You can update these announcements once, and apply them against all the respective instances. This feature provides a more efficient way to update auto attendants and allows you to update company-wide announcements. For example: a holiday announcement.​

You can set the announcement repository at organization level and location level.

The announcement repository option at the organization and location level provides these capabilities:​

  • Add, update, and delete the audio files​, including the generation of new audio files using Text-to-Speech.

  • Replace existing announcement files

  • Filter and sort capability to view the files​

  • Displays the file information and the feature instance that uses the announcement.​

  • Supports localization of the announcements

Before you begin

  • You can’t delete current files that the features use.

  • You can store announcement files with up to 1-GB storage limit across all the levels.

  • Ensure that you don’t upload announcement files with duplicate names.

  • Adhere to the following requirements when uploading the audio files:

    • Audio file format:

      • .WAV files with 8 or 16 kHz, 8-bit or 16-bit mono, µ-law, A-law, or PCM

      • .WMA files with 8 or 16 kHz, 16-bit mono, µ-law, A-law, or PCM

    • Maximum audio length:

      • 2 minutes for a voice message greeting and custom callback user/group.

      • 10 seconds for user's voice portal personalized name.

      • 10 minutes for the music on hold greeting.

      • 5 minutes for all other services.

    • Minimum audio length: 5 seconds

Generate a Text-to-speech announcement file

Before you begin

This feature efficiently and quickly generates prompts, greetings, and announcements using Text-to- Speech (TTS). It functions like a recorded WAV file, eliminating the need for manual recording.

Consider these pointers while using the Text-to-Speech feature:

  • Audio file format: .WAV files with 16 kHz, 16-bit depth, PCM

  • Language supported: English

  • Maximum text length: Text can have a maximum character length of 3000 characters.

  • Speech Synthesis Markup Language (SSML) tags: You can include Speech Synthesis Markup Language (SSML) tags in your Cloud Text-to-Speech requests to customize your audio output. The supported SSML tags from Voicea are:
