Kluczowe cechy

Style instructions, kept apart from the words

Write the exact words in the script and the delivery in Style Instructions ("warm and slow", "a dramatic newscast"). The script stays clean and the same text can be read several ways.

Steady over long reads

Google built 3.8 to keep voice identity, timbre, volume and room tone consistent across multi-minute narration, without the voice drifting partway through.

Inline vocal events

Add <laugh>, <sigh> or <short pause> inside the text where they should happen for a more natural, acted read.

30 voices, many languages

Thirty named voices, from Kore and Puck to Zephyr and Achernar. Google says the model detects the input language automatically and supports 130 languages.

Przypadki użycia

Audiobook and long narration

Read chapters and long explainers with a voice that stays the same from the first minute to the last.

One script, several reads

Keep the text fixed and change only the style instructions to get a calm, an upbeat and a dramatic version.

E-learning and training audio

Produce consistent narration across many lessons, with pauses placed exactly where learners need them.

Voice for a talking avatar

Generate the speech, then use it to drive an avatar model such as Kling Avatar V2.

Dogłębna analiza

What Gemini 3.8 Flash TTS is good at, and where it isn't

Gemini 3.8 Flash TTS is Google's flagship creative speech model, and its design choice is clear: keep the words and the direction apart. You paste exactly what should be said, and describe how it should be said in a separate style instruction. That keeps scripts clean, lets you try a calm, an upbeat and a dramatic read of the same text without touching it, and suits teams where one person writes and another directs.

The first flagship capability is long-form stability. Google built 3.8 to keep voice identity, timbre, volume and even the room tone consistent across extended narrations and long dialogues, so a ten-minute chapter does not slowly turn into a different voice. That is the main reason to choose it over Gemini 3.1 Flash TTS for audiobooks, courses and long explainers.

The second is precise acting cues. Style instructions are followed more closely than in 3.1, and inline vocal events such as <laugh>, <sigh> and <short pause> land where you put them. Google also lists support for regional accents and minority dialects, and says the model detects the input language automatically across 130 languages.

On ZOOOP you choose from 30 named voices; the style instruction is optional.

Where it's weaker: the voices are Google's prebuilt set, with no voice cloning or custom voices on ZOOOP, and two-speaker dialogue is not exposed yet, so generate each speaker separately. Tag-driven performances with ElevenLabs voices are Eleven V4's strength, and for Chinese-first projects Qwen3-TTS is a natural fit.

A reasonable mental model: use Gemini 3.8 Flash TTS for long narration and for reads you want to direct in plain language. Reach for Eleven V4 when you prefer audio tags and ElevenLabs voices, and Kling Avatar V2 to turn the voice into a talking video.
