What is this model like?

The current status is not Coming Soon. The model has a defined structure for speakers and dialogue, but the per-turn text limit cannot bound an entire request or its worst-case audio output. This site will not expose a generation entry point until safe preauthorization can be proven.

Selection guide

Use these decision points when choosing a model.

1
You must deliver a multi-speaker project now

Use ElevenLabs Dialogue V3 first to verify character separation and script pacing.

2
You need long-form narration now

Compare ElevenLabs Multilingual V2 with Turbo 2.5 first.

3
You want to track the release condition

Access requires a reliable output-audio limit; the model name alone cannot establish one.

Practical usage insights

Practical guidance based on public sources, current on-site limits, and representative tasks.

A Pro label does not close the settlement gap

Regardless of model tier, preauthorization must be proven not to underestimate cost before task creation.

Voice controls add evaluation dimensions

Voice, accent, style, and pacing should each be compared using the same script.

Capabilities

Character Voice Design

Each speaker can be assigned a voice, accent, audio profile, style, and pacing.

Multi-Turn Dialogue

Multiple dialogue turns are linked to speaker IDs and produced in sequence.

Scene and Tone Direction

Scene context and overall direction can describe the intended listening experience.

Use cases

Long-Form Audio Planning

Define characters and tone rules for extended narration or chapter-based content.

Multi-Person Interview Scripts

Separate host, guest, and narrator lines by speaker.

Voice Design Evaluation

Once generation opens, compare naturalness, character consistency, and actual credit usage.

Prompt tips

Lock the Cast List First

Avoid using multiple inconsistent IDs for the same speaker.

Keep the Scene Brief Concise

Describe the overall listening experience first, then place specific emotions in each character's configuration.

Test Proper Nouns in a Short Passage

Validate brand names, numbers, and foreign-language terms with a small sample first.

Why choose it

The multidimensional voice-control contract is clearly defined.
The model addresses emerging search interest in multi-character and long-form speech.
The unavailable state prevents users from being misled into starting a generation.

What to know first

Neither text-to-speech nor dialogue-to-speech requests can currently be started.
The speaker and dialogue arrays have no total item limit.
The output audio token ceiling cannot be reliably derived from the input.

ElevenLabs Dialogue V3

ElevenLabs Dialogue V3 provides line-by-line dialogue generation: enter each turn, choose a voice, and pay by total dialogue length. It is not a real-time voice agent, and ElevenLabs notes that users may need multiple generations to find a usable result. Start with a sample to check speaker changes, audio tags, language code, output format, and long-script completeness.

ElevenLabs Multilingual V2

ElevenLabs Multilingual V2 is Kyeo AI's current single-speaker, high-naturalness voiceover page. It shares a similar form with Turbo 2.5, but the task boundary differs: Turbo is a fast voiceover baseline, while Multilingual V2 is aimed at long-form narration, cross-language content, and sustained brand voice. Kyeo still uses a fixed voice list and a 5,000-character entry, so the practical decision is whether the listening experience justifies twice Turbo's per-character cost.

ElevenLabs Turbo 2.5

ElevenLabs Turbo 2.5 is a retained single-speaker TTS workflow on Kyeo AI. It exposes a voice choice plus stability, similarity boost, style, speed, timestamps, surrounding text, and language code. The workflow remains selectable, but ElevenLabs now recommends Flash v2.5 instead. The Turbo name does not make low latency, language support, timestamp accuracy, voice authorization, or output quality a Kyeo guarantee.

Source note

The speaker, dialogue, voice-control, and token-rate contract for Gemini 2.5 Pro TTS has been verified. However, the maximum number of output audio tokens cannot be proven before a request is created, so generation is not currently available on this site.
