Examples
Narrative scene
By the time the boat reached the island, the mist had lifted. A red roof appeared above the trees, and the harbor bell rang once.
Documentary passage
The workshop keeps a collection of simple tools. Their handles are worn smooth, each one carrying the memory of many careful hands.
Gentle closing
As we finish this session, take one idea with you. It does not need to be a large idea. A small question can be a useful beginning.
Museum description
The woven basket is light but strong. Its pattern repeats around the rim, showing how a practical object can also hold a quiet rhythm.
Reading invitation
Turn the page slowly. Notice where the sentence pauses and where the sound changes. Reading aloud lets the story reveal its shape.
At a glance
Is this model right for you?
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.
- What it does best
- A Gemini Pro speech candidate focused on multi-character work and fine-grained style and tone control.
- Who it is for
- People evaluating audiobooks, character dialogue, or extended narration who want to prepare rigorous listening samples.
- Why use it on Kyeo AI
- This page explains the current voice-design capabilities and why paid generation remains unavailable until a reliable maximum credit estimate can be calculated.

Decision guide
Still deciding? Start with these key decision points.
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.

Real-world experience
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.
