Brilo AI offers a broad set of spoken languages and multiple selectable synthetic voices. Availability for each language and accent depends on your account plan, the configured speech recognition and text-to-speech options, and any provider voices enabled for your account. Administrators can set an agent’s spoken language, choose a specific synthetic voice, and test calls before going live. Language detection, speech recognition, and voice selection can be configured per phone number or routing rule.

Will Brilo AI support Spanish or French? — Yes. Brilo AI supports many widely used languages; availability depends on your account and enabled TTS/ASR options.

Does Brilo AI handle different accents within a language? — Often yes. You can select voice models and accents when those options are provided for a language.

Can Brilo AI switch languages during a call? — When enabled, Brilo AI can be configured to detect language and route to the appropriate language workflow or request a human handoff.

Enterprise buyers ask this because language coverage affects global support operations, compliance workflows, and routing design. For regulated sectors like healthcare and financial services, language support determines whether calls can be automated safely, when agents must escalate, and what localization work is required. Decision-makers need to know practical limits—what languages are supported in production, whether accents and dialects are available, and what admin work is required to enable each language.

Brilo AI voice agent support is controlled by three linked settings: speech recognition to understand callers, the spoken language setting on the voice agent, and the text-to-speech voice model to speak back. When a call arrives, Brilo AI uses the configured speech recognition to transcribe the caller’s words, applies the active conversation model for intent and slot filling, and responds using the selected synthetic voice. Administrators can map languages to phone numbers, routing rules, or IVR choices so calls enter the correct language workflow.

In Brilo AI, spoken language is the configured language the voice agent uses to interpret and reply on a call.

In Brilo AI, synthetic voice is the selected TTS voice that the agent uses to speak responses.

In Brilo AI, speech recognition is the transcription layer that converts caller audio into text for the conversation engine.

Do not rely on Brilo AI for perfect understanding of rarely used dialects or unlisted languages unless explicitly tested and enabled in your account. Configure explicit escalation when confidence scores drop, when sensitive PII appears in free-text responses, or when regulatory requirements mandate a human. Language configuration is account-driven—unsupported languages must be routed to human teams or a fallback workflow. Do not assume simultaneous multi-language mixing on a single call unless you design automatic language detection and fallback rules.

In Brilo AI, language detection is the configured behavior that attempts to identify the caller’s language and route accordingly.

Brilo AI supports explicit handoffs when configured. Typical handoff options include transferring the call to a live agent, opening a callback ticket in your CRM, or routing to a specialist workflow. Configure guardrail rules so Brilo AI initiates a handoff when: language is unsupported, confidence score is below a threshold, a caller requests a human, or sensitive data is detected. Handoffs can include a short transcript summary and the detected language to reduce time-to-resolution for the receiving agent.

Brilo AI language support reduces the need for dedicated bilingual live agents for high-volume, low-complexity interactions while maintaining safety through guardrail-driven handoffs. Enterprises can scale 24/7 multilingual coverage, reduce customer hold times for basic inquiries, and improve routing accuracy so specialized human agents focus on complex or high-risk tasks. These outcomes are achieved by combining configured speech recognition, selected synthetic voices, and well-defined escalation policies.

Which languages are available out of the box?

Availability depends on your Brilo AI account plan and the enabled speech and voice options. Contact your Brilo AI administrator or account rep to see the current list for your environment.

Can I add a custom voice or dialect?

You can request or enable available voice models (synthetic voices) provided for a language. Custom voice creation or dialect tuning typically requires additional setup and provisioning—check your account options.

How does Brilo AI detect the caller’s language?

Language detection is based on configured detection rules and the speech recognition layer. You can route by caller-selected IVR choice, phone number, or automatic detection; always include fallback and escalation for low-confidence detections.

What happens if the agent misrecognizes words in a medical or financial call?

Configure strict confidence thresholds and immediate handoff rules for sensitive domains so any uncertain medical or financial content is escalated to a human.

Can Brilo AI speak multiple languages on the same phone number?

Yes—when you configure routing and language selection rules. Many customers map language choice to an IVR prompt, phone number, or automatic detection and then route to the appropriate language workflow.
