Activate and configure a third-party TTS provider integration

AI-generated summary

Genesys Cloud's Text-to-Speech (TTS) Connector provides standardized integration with multiple third-party voice synthesis 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 format at 8kHz regardless of provider capabilities and is designed exclusively for audio streams in interactive voice response workflows, not JSON body audio payloads or SSML implementations. Core configuration requires administrators to establish provider-specific settings through the Admin interface under Integrations, including Synthesize Text URI, List Voices URI, request methods, and 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 vary in their technical requirements. Acapela Cloud requires language and gender selection with OAuth credentials using login, email, and password fields. Cartesia utilizes OAuth credentials with sonic-3 model support and specific API endpoints for synthesis and voice retrieval. Deepgram requires API key authorization and does not support SSML tags as of July 2025. ElevenLabs requires xi-api-key credentials with eleven_flash_v2_5 model configuration and output format mapping. Emotech offers multiple Arabic and English voice options with gender-specific variants. ReadSpeaker supports EU endpoint configuration with various sample rates and output format parameters. The activation workflow involves accessing Admin > Integrations, searching for the Genesys TTS Connector, configuring provider-specific properties and credentials through Configuration and Credentials tabs, completing advanced JSON configuration settings, and changing integration status from Inactive to Active. Administrators should assign unique, descriptive names to each integration instance for organizational clarity. The integration is not PCI-compliant and cannot be used in secure flows. Genesys recommends using shorter TTS text to minimize latency, as providers are in Limited Availability and may experience latency issues. Related resources include documentation on TTS engines, the AppFoundry, Architect, BYOT migration options for Google and Microsoft Azure TTS integrations, and Audio Connector materials

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.
The Genesys TTS Connector integration is not PCI-compliant and therefore cannot be used in secure flows.

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.
