Speech 2.5 Prompts
MiniMax's multilingual voice synthesis model — one voice pipeline, many languages, and a knack for sounding like a native rather than a machine.
About Speech 2.5
Speech 2.5 is MiniMax's multilingual voice synthesis model. It converts text into speech across a wide range of languages, with voices that stay natural and consistent rather than slipping into the flat, robotic cadence that multilingual systems often have.
Its core strength is exactly that combination: breadth of language coverage plus naturalness within each one. The same project can ship narration in several languages without the voice quality dropping off at the borders — which is what makes it a practical choice for localized content, not just single-language demos.
But naturalness is a two-way contract: the model renders what you wrote, and text that was translated word-for-word will sound translated. Scripts written the way a native speaker would actually phrase them are what unlock the model's ceiling. The gallery below collects tested Speech 2.5 prompts with their real audio, so you can hear the difference a well-localized script makes.
How to write Speech 2.5 prompts
- 1Write the script natively in the target language, not as a literal translation. Word-for-word renderings carry the source language's rhythm, and the voice will faithfully reproduce that awkwardness.
- 2Use punctuation as your pause system: commas for short breaths, periods for full stops, and split any sentence you can't read aloud in one breath.
- 3Spell out numbers, dates, and abbreviations the way they should be heard — "twenty twenty-six", not "2026" — especially in languages where the written form is ambiguous.
- 4Keep one language per segment where you can. If a foreign word must appear, keep it short and common; heavy code-switching mid-sentence is where any multilingual voice is most fragile.
- 5Match the register to the use case: a news read, a bedtime story, and an app notification each want different sentence lengths and formality. The voice follows the writing.
- 6When localizing one script into several languages, adapt idioms and examples per locale instead of copying them across — a metaphor that sings in one language lands flat in another.
Frequently asked questions
What languages does Speech 2.5 support?
It is built as a multilingual model and covers a wide range of languages within one voice pipeline. The practical benefit: you can produce localized versions of the same content while keeping voice quality consistent across languages.
Why does my Speech 2.5 output sound unnatural?
The most common cause is the script, not the voice: literally translated text keeps the source language's rhythm and word order. Rewrite the passage the way a native speaker would phrase it, break up long sentences, and the delivery usually snaps into place.
Can Speech 2.5 mix languages in one clip?
Short foreign words and names inside a sentence generally work. For longer passages, switching languages at segment boundaries is far more reliable than dense mid-sentence code-switching, which is the hardest case for any multilingual voice model.
Where can I try these Speech 2.5 prompts?
Speech 2.5 is available through MiniMax Audio and the MiniMax open platform for developers. Copy a prompt from this page, paste the script, pick a voice and language, and adjust the phrasing to your locale.
