Available in Ailoot inputs, outputs and options are listed for the selected method below. #### Fast synthesis of conversational lines Speech 2.8 Turbo combines fast audio production with natural variation in the voice. The manufacturer positions Turbo for fluent conversational sound: short lines, text narration and voice interaction. This card accepts text and returns speech audio. #### Laughter, breathing and interjections Like the HD version of this generation, Turbo supports Speech 2.8 audio markers. Text can include markers for laughter, chuckling, coughing, throat clearing, inhaling, exhaling, sighing and other short sounds. This controlled variation makes a line resemble conversation, introducing breaths and pauses connected to the content. An audio marker applies to a specific place in the text. The model's defined parenthesized markers are used for this, such as `(laughs)` or `(breath)`. An arbitrary effect description is not an equivalent substitute for a supported marker. #### Voice and language The Speech 2.8 family supports **40 languages**, including Russian, and work with prepared voices. The manufacturer highlights recognizable vocal texture, breathing characteristics and reduced digital distortion. Cloning capability concerns separate voice preparation, after which the voice can be used in synthesis. MiniMax provides voice selection and control over pace, volume and pitch. Speed ranges from **0.5–2**, volume is above 0 and up to **10**, and pitch adjustment ranges from **−12 to 12**. Emotion can be left to the model according to the text's meaning or specified manually: joy, sadness, anger, fear, disgust, surprise or calm. Pronunciation can be refined using a replacement dictionary and phonetic notation; these provide the International Phonetic Alphabet, Chinese pinyin and Japanese reading variants. Pauses are inserted between spoken passages in the range **0.01–99.99 seconds**. Pause duration is specified to two decimal places; markers are placed between spoken passages and not consecutively. These settings help align names, abbreviations and ambiguous words with the intended narration. #### Incremental output and audio format Synthesis accepts text of fewer than **10,000 characters**. For long text exceeding 3000 characters, the manufacturer recommends streaming output; receiving completed audio in full is also provided. General synthesis settings include MP3, PCM, FLAC, WAV, Opus and G.711 μ-law variants, in mono or stereo; the available formats for a specific request are determined by Ailoot's controls. Turbo's speed is a characteristic of the model variant, not a promise of fixed latency for a completed line. No numerical request latency is specified here. The listed extended manufacturer settings require support in the selected access method through Ailoot. Additional audio settings include sample rates of **8, 16, 22.05, 24, 32 and 44.1 kHz**. MP3 provides bitrates of **32, 64, 128 or 256 kbps**. Voice coloration can also be changed and one effect applied: spacious echo, hall echo, telephone sound or a robotic voice. Voice-modification effects are supported for MP3, WAV and FLAC when receiving the audio in full, and only for MP3 when streaming. G.711 μ-law formats use an 8 kHz sample rate. These capabilities belong to MiniMax's synthesis settings. The manufacturer provides speech-text synchronization: sentence timestamps, word timestamps or word timestamps during incremental output. This result helps align speech with displayed text. This additional capability requires support for the corresponding response format. **Ailoot Ultra · Text to speech** `POST /v1/audio/speech` `minimax/speech-2.8-turbo` [`minimax/speech-2.8-turbo`](https://ailoot.ai/models/en/#m=minimax%2Fspeech-2.8-turbo&route=Ultra&caller=minimax%2Fspeech-2.8-turbo&fmt=speech) MiniMax /`minimax/speech-2.8-turbo` ### Overview Speech 2.8 Turbo provides fast synthesis of natural speech with audio markers and expressive control.
