Minimax 2.5
Minimax Speech 2.5 HD is the best text-to-speech model for Mandarin Chinese and multilingual voiceovers. While ElevenLabs dominates English-language TTS, Minimax Speech handles Chinese tonal accuracy with a naturalness that Western TTS models cannot match — the four Mandarin tones, sentence-level intonation, and emotional cadence all sound native rather than robotic. The model offers 17 distinct voices at 10 credits per ~100 characters (HD) or 6 credits per ~100 characters (Turbo variant), making it cost-competitive with ElevenLabs while offering superior CJK language support.
Minimax Speech comes in two quality tiers: HD (10 credits/~100 chars) and Turbo (6 credits/~100 chars). HD produces richer prosody with more natural breath pauses, tonal variation, and emotional range — use it for final deliverables. Turbo is 40% cheaper with slightly less nuanced intonation — use it for drafts, internal reviews, and quick iterations. For a 500-character Chinese narration, HD costs approximately 50 credits vs Turbo's 30. The quality difference is most audible in longer narrations where HD's natural pacing prevents the "robotic monotone" that builds over extended text.
Minimax Speech offers 17 voices, each designed for a specific speaking persona. For corporate product narration, "Elegant_Man" or "Calm_Woman" provide professional, measured delivery. For educational tutorials, "Friendly_Person" or "Patient_Man" sound approachable and clear. For youth-targeted marketing, "Lively_Girl," "Exuberant_Girl," or "Casual_Guy" bring energetic, conversational delivery. For authoritative voiceovers (documentaries, brand announcements), "Deep_Voice_Man" or "Imposing_Manner" convey gravitas. Always test your chosen voice with a 2-3 sentence sample before committing to a full script — voice character can change noticeably between short and long passages.
Minimax Speech has no explicit speed or pacing parameters — you control rhythm entirely through punctuation and text structure. Use periods to create full pauses between sentences. Use commas for brief pauses within sentences. Use ellipses (...) for dramatic pauses. For Chinese scripts, use Chinese punctuation marks (。，、) which Minimax interprets with correct tonal cadence. For bilingual scripts (Chinese + English mixed), the model handles code-switching naturally — you can include English brand names, product terms, or technical vocabulary within Chinese sentences and Minimax will pronounce them correctly without breaking the flow.
For projects targeting Chinese-speaking audiences, generate the same script with both Minimax Speech HD and ElevenLabs v3 to compare. Place both Audio nodes on the Martini canvas and listen back-to-back. In most Chinese narrations, Minimax will sound more natural — especially for four-tone accuracy and sentence-level prosody. For English-only narrations, ElevenLabs typically has an edge in emotional expressiveness. For bilingual content, Minimax is usually the better choice because its code-switching (Chinese sentences with English terms) sounds seamless, while ElevenLabs may struggle with the tonal shift between languages.
Chinese product narration — demonstrates Minimax's core strength: natural Mandarin tonal accuracy. The formal register ("您" polite form) combined with persuasive copy structure tests whether the model can maintain professional warmth throughout. Listen for natural rhythm at the commas and whether the final sentence lands with conviction rather than trailing off.

English tutorial narration — tests Minimax's English capability against its Chinese strength. The conversational, instructional tone ("we'll show you how to") requires a friendly, unhurried pace. Compare this output with ElevenLabs to calibrate where each model excels. For English-only content, ElevenLabs usually sounds more expressive; for mixed-language content, Minimax wins.

Minimax Speech has no parameters beyond voice selection — all control comes from your text formatting. Use punctuation as your pacing tool: periods for full stops, commas for breath pauses, ellipses for dramatic pauses, and em-dashes for abrupt shifts in tone.
HD costs 10 credits per ~100 characters; Turbo costs 6 credits per ~100 characters. For a typical 300-word English narration (~1,800 characters), expect approximately 180 credits (HD) or 108 credits (Turbo). Draft in Turbo, finalize in HD.
For Chinese content, always use HD — the quality difference is most pronounced in tonal languages where Turbo sometimes flattens the second and fourth tones. For English content where Minimax is already less expressive than ElevenLabs, Turbo is often sufficient.
The 17 available voices span professional (Elegant_Man, Calm_Woman), energetic (Lively_Girl, Exuberant_Girl, Casual_Guy), authoritative (Deep_Voice_Man, Imposing_Manner), and warm (Friendly_Person, Patient_Man) personas. Match voice to content type rather than defaulting to the same voice across all projects.
Minimax Speech 2.5 HD is the definitive choice for Chinese-language voiceovers — its tonal accuracy, natural prosody, and code-switching ability are unmatched by any Western TTS model including ElevenLabs. For English-only content, ElevenLabs v3 still has an edge in emotional expressiveness (21 voices, nuanced delivery via punctuation-driven pacing), but Minimax is a credible alternative at the same price point (10 credits/~100 chars for both). For bilingual Chinese-English content, Minimax is the clear winner — its seamless language switching produces narration that sounds like a single bilingual speaker rather than two models stitched together. The ideal voiceover workflow on Martini: use Minimax Speech for Chinese and bilingual content, ElevenLabs for English-only content.
