Voice agents that understand, adapt and act, Like a human

An IVR requires multi-choice menus and only understands predefined keywords. A Volubile agent understands natural language in all its complexity — long sentences, accents, hesitations, multiple intentions — and maintains context throughout the call. The caller speaks naturally, the agent understands and acts.

It's the time between the end of the caller's sentence and the beginning of the agent's response. Below 800ms, this latency is imperceptible to the human ear — the threshold below which a conversation feels natural. It's achieved through a fully asynchronous STT + LLM + TTS pipeline: transcription, generation, and synthesis run in parallel, with audio playback starting even before processing is complete.

Volubile's proprietary VAD (Voice Activity Detection) system dynamically adjusts silence thresholds based on the conversation's context. If the caller interrupts the agent, the conversational context is immediately re-injected — the agent picks up seamlessly without losing any exchanged information. No dead air, no repeating, no "I didn't catch that."

Yes. The speech recognition engine is trained on real conversational data — not just on articulated speech. Regional accents, hesitations, unfinished sentences, mid-sentence corrections: the agent maintains understanding and context without asking the caller to rephrase.

Yes. Volubile allows you to replicate an existing voice — a brand voice, a voice actor's voice, or an internal advisor's voice — and associate it with your agents. Once cloned, the voice can be configured for speed, pitch, and expressiveness just like any voice from the library. Cloning is subject to the explicit consent of the voice owner.

Yes. Frustration, confusion, urgency: detected in real-time during the call. The agent's tone and pace automatically adjust — more composed for a complaint, more dynamic for a sales qualification. This adaptation is particularly useful for sensitive calls: claims, overdue payments, critical support.

From the very first seconds, the agent detects the spoken language and adapts to it. If the caller switches languages during the conversation — a common occurrence in Belgium, Switzerland, or international markets — the transition is immediate and seamless: no redirection, no interruption, no requests for repetition. Over 50 languages are available, with voice and pronunciation independently configurable for each.

Volubile's phonetic configuration allows you to define the exact pronunciation word by word in each activated language. Brand names, product references, industry abbreviations, acronyms: anything a generic dictionary would mispronounce can be precisely corrected. Configuration is done directly from the interface, without technical intervention.

The library includes 100+ ultra-realistic voices — female, male, and neutral — available in numerous languages and regional variants. Each voice can be configured for speed, pitch, and expressiveness. You can test the voices in real-world conditions from the sandbox before any production deployment.

Yes. The same quality—latency, comprehension, and response consistency—is guaranteed whether the agent handles 1 call or 3,000 simultaneously. The infrastructure is scaled for peak loads without noticeable degradation. The 99.8% SLA is measured in production across all active clients.
