<h2>Abstract</h2>
<p style="text-align: left;">
We introduce MiniMax-Speech, an autoregressive Transformer-based Text-to-Speech (TTS) model that generates
high-quality
speech. A key innovation is our learnable speaker encoder, which extracts timbre features from a reference audio
without
requiring its transcription. This enables MiniMax-Speech to produce highly expressive speech with timbre
consistent with
the reference in a zero-shot manner, while also supporting one-shot voice cloning with exceptionally high
similarity to
the reference voice. In addition, the overall quality of the synthesized audio is enhanced through the proposed
Flow-VAE. Our model supports 32 languages and demonstrates excellent performance across multiple objective and
subjective evaluations metrics. Notably, it achieves state-of-the-art (SOTA) results on objective voice cloning
metrics
(Word Error Rate and Speaker Similarity) and has secured the top position on the public TTS Arena leaderboard.
Another
key strength of MiniMax-Speech, granted by the robust and disentangled representations from the speaker encoder,
is its
extensibility without modifying the base model, enabling various applications such as: arbitrary voice emotion
control
via LoRA; text to voice (T2V) by synthesizing timbre features directly from text description; and professional
voice
cloning (PVC) by fine-tuning timbre features with additional data.

<p>
ZeroShot maintains speaker identity while generating more natural emotions, pauses, and other expressive
features based
on the text content, whereas OneShot adheres more strictly to the speaker characteristics (prosody, speech
rate,
emotions, etc.). For details of Zero-Shot and One-Shot, refer to the <a
