Available in Ailoot inputs, outputs and options are listed for the selected method below. #### A natural voice for interaction Speech 2.6 HD is intended for natural speech synthesis and scenarios where beginning a response quickly matters. The manufacturer focuses on intonation, speech fluency and text processing before delivery. The HD variant emphasizes audio quality; this card's input is text and output is speech audio. #### Reading unconventional written forms The Speech 2.6 generation can process forms often found in working messages: URLs, email addresses, phone numbers, dates and monetary amounts. The model converts them into spoken forms so a line remains understandable by ear. The manufacturer describes these tasks in several languages. #### Fluent speech while preserving timbre Speech 2.6 provides Fluent LoRA, a fluency enhancement mode. It is intended for synthesis using a prepared voice: it helps retain timbre while producing more connected speech, even if the original sample was uneven or accented. Preparing a cloned voice and using it for narration are different actions. **40 languages** are supported, including Russian. Alongside seven basic emotional states, Speech 2.6 provides the fluent-speech option `fluent` and whisper option `whisper`. If no emotion is specified, the model chooses it from the text's meaning. #### Delivery settings 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. #### Text length and audio 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. According to MiniMax, the generation targets low latency in voice scenarios. This describes the model; actual response time and availability of extended settings depend on the selected Ailoot access method. 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 · Text to speech** `POST /v1/audio/speech` `speech-2.6-hd` [`speech-2.6-hd`](https://ailoot.ai/models/en/#m=speech-2.6-hd&route=Core&caller=speech-2.6-hd&fmt=speech) MiniMax /`speech-2.6-hd` ### Overview Speech 2.6 HD is a high-quality speech synthesis model focused on naturalness and voice similarity.
