Activate and configure a third-party TTS provider integration

AI-generated summary

Genesys Cloud's Text-to-Speech (TTS) Connector provides standardized integration with eight third-party TTS providers—Acapela Cloud, AWS Polly, Google Cloud, Deepgram, Cartesia, ElevenLabs, Emotech, and ReadSpeaker—allowing organizations to configure up to 10 integration instances. The connector standardizes all audio output to PCM format at 8kHz and functions exclusively with audio streams in interactive voice response workflows, not JSON body payloads or SSML tags, with the exception that Deepgram does not support SSML tags as of July 2025. Configuration requires administrators to access Admin > Integrations, locate the Genesys TTS Connector, and complete setup across multiple tabs. The Details tab allows assignment of unique integration names for identification. The Configuration tab requires entering specific property values including Synthesize Text URI, List Voices URI, request methods, and attribute mappings for text, voice, language, output format, and sample rate parameters. The Advanced tab accepts JSON-formatted configuration for voice mapping (supporting multiple languages including English, Arabic, and Japanese variants with customizable gender and voice model settings) and output format mapping (audio/L16 and audio/mpeg formats). The Credentials tab stores provider-specific authentication using the ttsConnectorUserDefinedPathAuth credential type, with each provider requiring distinct API keys or authorization tokens—including OAuth credentials for Cartesia, API keys for Deepgram, xi-api-key for ElevenLabs, and Authorization Tokens for other providers. Provider-specific implementations vary in supported features and configurations. Acapela Cloud supports multilingual voice mapping across multiple English and Arabic variants. Cartesia requires OAuth credentials and sonic-3 model specification. Deepgram uses API key authorization without SSML support. ElevenLabs requires xi-api-key credentials and eleven_flash_v2_5 model configuration. Emotech provides multiple Arabic and English voices. ReadSpeaker supports EU endpoint configuration with sample rates of 8000, 16000, and 22050 Hz. Administrators can optionally designate PCI compliance status through the PCI Compliant property; selecting True enables use in secure flows but requires the organization to assume compliance responsibility and review the PCI DSS customer responsibility matrix. After completing all configuration steps, administrators must change the integration status from Inactive to Active to enable functionality. Installation of the Genesys TTS Connector is required if not previously deployed to the organization. Call flows begin audio streaming immediately upon receiving audio from the provider, while bot flows wait for the entire audio payload before playback, resulting in additional latency.

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.
Genesys TTS Connector does not support Google Chirp 3 TTS voices.

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. Genesys recommends using shorter TTS text to minimize latency. Call flows begin audio streaming immediately upon receiving audio from the provider. Bot flows do not support audio streaming and instead wait for the entire audio payload to be received before playback. Consequently, additional delays can be expected when using bot flows.
