ElevenLabs vs Gemini Flash TTS

Versely serves both. ElevenLabs Multilingual is multilingual text-to-speech powered by ElevenLabs Multilingual v2, 8 credits per 1,000 characters, text-to-audio. Gemini 3.8 Flash TTS is Google’s expressive speech row: 30 voices, natural-language style direction, inline audio tags ([sigh], [laughs]), multilingual synthesis, two-speaker dialogue, 2 credits per 1,000 characters. The older Gemini 3.1 Flash TTS is still in the catalog at 12. Both write a voice file. Neither draws a mouth. If the cut shows a jaw, you still need a still and a lipsync pass after this file exists.

This is not ElevenLabs Music versus Suno, and it is not a dubbing-engine bake-off. Dubbing is dub a video, where ElevenLabs is one video engine among others. This page is two TTS catalog rows.

Both rows write audio, not a mouth

ElevenLabs Multilingual: content type audio, category text-to-audio, audio true on the card, no image required, no duration chip, no resolution. You type. You get speech. The listed job is multilingual TTS.

Gemini 3.8 Flash TTS: content type audio, category text-to-audio, no image, no duration chip, no resolution. The audio flag on that row is false because this catalog uses that flag for video generates with a soundtrack. Flash TTS is the soundtrack. Treat it as a file you attach, not a clip that already has a face.

The door for both is AI text to speech. Audition the same sentence on both before you commit a 900-word script. Speech billing follows the characters you send, not the seconds you get back. Cutting words is the only way to cut that meter. Playback speed is not a discount.

What neither row does:

• Invent a presenter. No still in, no still out.
• Viseme a line onto a plate. That is AI lipsync.
• Translate a finished video into another language while cloning the original delivery. That is dubbing.
• Write a song. Suno is a different shelf.

A closed mouth with this wav laid under it is a routing miss, not a TTS miss. If we see the mouth, change the row after the wav exists. If we never see the mouth — VO under b-roll, a phone-hold, a cutaway — you are done when the file lands.

When ElevenLabs is the read

Use ElevenLabs Multilingual when the job is a multilingual read you already trust as an ElevenLabs voice, or when the rest of the week already lives in that voice library.

Typical jobs:

• A VO you will reuse across languages on the same voice character, where Multilingual v2 is the engine you mean.
• A read that has to match other ElevenLabs assets already in the campaign (ads, in-product voice, a cloned line from a different workflow).
• Teams that already directed the voice on ElevenLabs and do not want a second speaker family in the same cut.

8 credits per 1,000 characters is the listed figure on this SKU. It is not the 2-credit Google file. Paying 8 is rational when the voice identity is the brief. Paying 8 because “ElevenLabs is the good one” while you actually needed tags and a 30-voice roster is how you skip Flash TTS’s job.

ElevenLabs Voice Change is a different published slug: audio-to-audio, from 20 credits (4 per second of output), voice conversion that preserves speech content. Do not send a script to Voice Change and expect TTS. Do not send a wav to Multilingual and expect conversion. Name the card.

Dubbing with an ElevenLabs engine on a locked video is still not this page. Runtime, trim windows, and language coverage for dub_video live on the dubbing task. TTS is how you create a line from text. Dubbing is how you replace a line that already exists in a file.

When Flash TTS is the read

Use Gemini 3.8 Flash TTS when the performance notes live in the script: which of 30 voices, how they say it, a [sigh] on one clause, a second speaker entering, a laugh that has to sit on a word.

Typical jobs:

• Multi-speaker dialogue as audio — two names in the prompt become two voices on one file, not two faces.
• A line that needs inline tags more than it needs an ElevenLabs library voice.
• Multilingual synthesis when you are already in Google’s voice set and 2 credits per 1,000 characters is the listed pass.
• Scratch reads you will throw away if the sentence is wrong. 2 credits is a cheaper sketch than 8, still not free, still not a talking generate.

Tags steer delivery, not the plate. [laughs] changes how the take is performed. It does not open a jaw. Natural-language style direction is the same class of lever: warmer, slower, a second speaker. Useful. Still audio.

Long blocks flatten even with a tag at the top. Chunk at the sentence. That is true on Flash TTS the same as on any other speech engine. Audio tags punch a moment. They do not typeset a face.

Multi-speaker is the other trap. A two-hander in the script is two performances on one file. If each speaker needs a picture, you still need plates and a lipsync pass after this file exists.

Do not infer a presenter because the same vendor ships Veo and Omni. Google’s roster on Versely includes video rows. Flash TTS is not those rows.

The mouth is a later row

Order, when we see the mouth:

1. Lock the still on an image row.
2. Generate the wav here — ElevenLabs Multilingual or Flash TTS, by the voice brief, not by habit.
3. Run a lipsync SKU. Kling Avatar Pro is one 4K talking-avatar card if that is the job. Other lipsync rows exist. This page does not rank them.
4. Caption the talking take. Add captions transcribes what was said.

If you only needed the line, stop after step 2.

Hume Octave 2 is not on this bake-off. Versely does not serve Octave 2, and Hume is sunsetting its TTS API, with access ending on 13 November 2026 (Hume changelog). Do not invent an Octave slug.

Article 50 still applies if you publish a realistic synthetic voice of a real person as authentic-looking (or sounding) media in the EU. A TTS file of a generated character is a different object from a clone of a named human. Know which one you made. Article 50 disclosure is the label copy when the rule applies.

Audition one sentence on both rows. Keep the engine that put the emphasis where you meant it. Sign up and run TTS as a wav, not as a talking generate.

FAQ

Does Gemini 3.8 Flash TTS make a talking video?

No. It is text-to-audio. You get a voice file: 30 voices, style direction, tags, multilingual, two speakers. The mouth is a lipsync or talking-head row that wants a plate.

Does ElevenLabs Multilingual include the dubbing engine?

No. This SKU is TTS from text. dub_video with an ElevenLabs engine translates and clones delivery on an existing file, up to 30 minutes, no mouth retarget on that engine. Different tool, different inputs.

Why is Flash TTS cheaper on the sticker?

2 credits versus 8 per 1,000 characters is the catalog. You are choosing a Google tagged read versus an ElevenLabs Multilingual v2 read. Pick the voice brief. Do not pick the 2 because it is 2 if the campaign already lives in an ElevenLabs speaker.
