About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

#### Lifelike speech with small audio details

Speech 2.8 HD targets natural, clean sound. The generation's main feature is audio markers that allow conversational details to be included in speech: laughter, chuckling, breathing, inhaling, exhaling, sighing, coughing, throat clearing and other short sounds. They help convey the rhythm and pauses of a natural line without turning every phrase into uniform announcer-style reading.

Markers are inserted into the text in the form specified for the model: for example, `(chuckle)`, `(breath)` and `(sighs)` indicate the corresponding vocal actions. Audio-marker capability belongs specifically to Speech 2.8. These are vocal details within speech synthesis, not generation of a separate musical or sound composition.

#### Timbre and clarity

The manufacturer highlights reproduction of distinctive voice characteristics: texture, breathing and pronunciation style. Family capabilities include synthesis with an already prepared cloned voice; creating that voice is a separate process. Speech 2.8 also has reworked processing to reduce background noise and digital distortions.

#### Languages and expressiveness

Speech 2.8 supports **40 languages**, including Russian. The manufacturer separately describes work on cross-language pronunciation in a Chinese-Japanese combination. This scenario concerns preserving natural sound when using different languages, not automatic text translation.

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.

#### Audio result

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.

This card turns text into speech audio. Voice settings describe the MiniMax model; creation of a voice clone, separate subtitles and specialized connection methods are not automatically included in a text-to-speech request.

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.
