Eleven v4 TurboNow in ElevenAgents

Our fastest and most expressive voice model built for live conversation, now on customer calls in 90+ languages.

Voices that build trust
in every conversation

Eleven v4 Turbo in ElevenAgents understands the conversation as it unfolds and adjusts to the caller's emotion mid-call — calmer when they're frustrated, clearer when they're confused.

Adjusting the tone mid-call

The agent understands frustration, hesitation, or hurry and adjusts its tone mid-call. Audio tags and conversation context let you steer it further.

90+ languages and accents

Any voice can speak every language your agent supports, and can switch mid-call.

Portuguese

A system built for natural, human-like delivery

Turn-taking that feels human

The agent stops mid-word when a caller cuts in, takes the correction, and answers the new question in the same turn.

Consistent, accurate tone

Voices keep the same identity across turns and languages, so every call sounds like your brand.

Agents with a sense of place

Background context and the sound of the room: a quiet studio, a soft office, or telephony-band realism.

Conversations that never stall

Eleven v4 Turbo turns text into audio as it’s generated, meaning replies play the instant they’re ready.

Oscar Daniels, Head of Credit Building Products, Spring Financial

With v4, users are connecting with the agent’s voice on a new level and we're already seeing increased user engagement. A smoother flow, improved responsiveness and clear pronunciation make interactions feel fluid.

Mikael Myhrberg, Automation Lead, PostNord

Our latency was already very good, and v4 reduced it considerably. The difference in customer service is immediate: the conversation flows even more naturally, without that silence that breaks the rhythm.

Mark Stewart Mello, Solutions and Experience Manager, Inter

The tone is more consistent and engaging throughout the conversation, and it adapts according to the stage of the interaction. It is a clear step forward in terms of quality and conversational experience.

Gabriele Luciani, Innovation Project Manager, Autotorino
