MiniMax: Speech 2.8 HD

MiniMax: Speech 2.8 HD is a text to speech model from MiniMax. It belongs to the speech category and is built for turning written text into spoken audio. MiniMax provides the model, and on api14 it is served under the model id minimax/speech-2.8-hd. If you already know MiniMax's speech lineup, this is the HD variant of Speech 2.8, positioned for applications where the generated audio is the product rather than a side effect.

The model takes text as its only input and produces speech as its only output. There is no context window figure listed for it, which makes sense for a synthesis model: you send the text you want spoken, and you get audio back. The model accepts arbitrary MiniMax voice IDs, so you are not restricted to a fixed roster. A large set of English voices is available, covering a wide range of delivery styles and personas. Examples include English_expressive_narrator, English_magnetic_voiced_man, English_CalmWoman, English_Whispering_girl, English_AnimeCharacter, English_MatureBoss, English_WiseScholar and English_Comedian. The range runs from narrators and storytellers to character voices, so tone can be matched to the content rather than settling for a single default.

Because the output is audio, the practical uses follow from what you feed it. Narration for videos, audiobooks and long form articles is a natural fit, especially with voices like English_expressive_narrator or English_CaptivatingStoryteller. Assistive reading tools can turn documents, articles or messages into speech for users who prefer listening. Voiceovers for ads, explainers and product demos work with the more assertive or upbeat voices. Games and interactive apps can use the character oriented voices, such as English_AnimeCharacter or English_PlayfulGirl, for dialogue and prompts. Support and IVR style systems can use calm or trustworthy voices for spoken responses. Any pipeline that already produces text and needs a spoken version can call this model as the final step.

You call it through api14's OpenAI-compatible API using the model id minimax/speech-2.8-hd. Because the interface follows the OpenAI format, you can point an existing OpenAI client at api14 and request this model without rewriting your integration. The model's supported parameters list is empty, so there are no additional tuning parameters documented for it. In practice you supply the text to be spoken and select a voice, either one of the listed English voices or another MiniMax voice ID. There is no listed maximum output length, so treat very long scripts with care and consider splitting them into smaller requests if you need predictable latency.

Given the empty parameter list, this model is a straightforward choice when you want speech out and do not need fine grained control over the synthesis. If your application needs a different output modality, such as text or images, a model from another category on api14 would fit better. If you need to pick among several speech options, compare the available voices and the audio quality each one targets, since voice selection is the main lever this model exposes.
