Activate and configure a third-party TTS provider integration

AI-generated summary

Genesys Cloud's Text-to-Speech (TTS) Connector provides comprehensive integration capabilities with multiple third-party providers including Acapela Cloud, AWS Polly, Google Cloud, Deepgram, Cartesia, ElevenLabs, Emotech, and ReadSpeaker, supporting up to 10 integration instances per organization. The system standardizes all audio output to PCM at 8kHz regardless of provider format capabilities and is designed exclusively for audio streams in interactive voice response workflows, not JSON body audio payloads. Core configuration across all providers requires setting Synthesize Text URI, List Voices URI, request methods, and essential attribute mappings for text, voice, language, and output formats. Authentication is managed through provider-specific API keys or authorization tokens configured via the Credentials tab using the ttsConnectorUserDefinedPathAuth credential type. The platform supports advanced JSON-formatted voice mapping for multiple languages including English, Arabic, and Japanese variations, with customizable gender and voice model settings. Provider-specific implementations include Acapela Cloud with voice mapping for languages (en-AE, en-AU, en-us, ar-001) and gender selection, Cartesia with OAuth credentials and sonic-3 model support, Deepgram with API key authorization (though without SSML tag support as of July 2025), ElevenLabs with xi-api-key credentials and eleven_flash_v2_5 model configuration, Emotech with multiple Arabic and English voices, and ReadSpeaker with EU endpoint configuration supporting various sample rates (8000, 16000, 22050 Hz). The activation process involves accessing Admin > Integrations, searching for the Genesys TTS Connector, configuring provider-specific properties and credentials through the Configuration and Credentials tabs, completing advanced JSON configuration settings for voice and output format mapping, and changing the integration status from Inactive to Active. All integrations require initial installation into the Genesys Cloud organization if not previously deployed, enabling organizations to deploy standardized TTS capabilities across their communication infrastructure.

Feature coming soon

You can configure the Genesys TTS Connector integration in Genesys Cloud to use your preferred third-party text-to-speech (TTS) provider. To integrate with a third-party TTS provider, you must set the integration properties, attributes, and credentials that are required to access their API endpoint.

Notes:

You can configure up to 10 Genesys TTS Connector integration instances for an organization.
TTS audio plays as PCM and 8kHz regardless of the formats the TTS provider supports.
Genesys TTS Connector does not support audio payload in the JSON body (Google TTS voices) or SSML (Microsoft Azure custom voices). TTS Connector supports only audio streams.

Refer to the following sample configuration for each third-party TTS provider that Genesys Cloud currently supports:

Note: Genesys has validated these providers through testing. Because they are in Limited Availability, customers may experience latency issues. Genesys recommends using shorter TTS text to minimize latency.
