Installing local TTS speech engines

Last Updated : Mar 11, 2025 |

Local TTS uses RPM files, one for each language, installed on the same server as the voicemail service.

  • Local TTS is supported by PLDS licenses and subscription IP Office system. Languages are added by installing files on the same server as the Voicemail Pro service.

    • PLDS licensed IP Office systems require TTS licenses.

    • Subscription IP Office systems do not require any additional subscriptions.

  • Languages: Brazilian (Portuguese), Chinese (Mandarin), Danish, Dutch, English (UK), English (US), Finish, French, French (Canadian), German, Greek, Norwegian, Polish, Portuguese, Russian, Spanish, Spanish (Colombian) and Swedish.

Note:
  • If Google speech is also enabled on the system, use of Google speech for TTS overrides locally installed TTS.
