End-to-End Training for Discrete Token LLM based TTS System

arXiv:2606. 09234v1 Announce Type: cross Abstract: Recent state-of-the-art (SOTA) text-to-speech (TTS) systems typically adopt a cascaded pipeline consisting of a speech tokenizer, an autoregressive large language model (LLM), and a diffusion based flow-matching (FM) model, with these components trained independently.

Phoneme-Guided Initialization for LLM-based Speech Recognition

The paper introduces phoneme‑guided initialization for large language model‑based speech recognition. By pre‑training an audio encoder on speech‑to‑phoneme conversion and an LLM on phoneme‑to‑grapheme conversion, then fine‑tuning jointly on ASR, the method leverages phoneme‑mediated processing within an end‑to‑end framework. Experiments on Japanese, Chinese, Tatar, and Urdu demonstrate that this approach matches or surpasses both cascaded S2P‑P2G baselines and end‑to‑end models without phoneme initialization.

BRIDLE: Generalized Self-supervised Learning with Quantization

BRIDLE is a self‑supervised encoder pretraining framework that extends bidirectional training to audio, image, and video by incorporating residual quantization (RQ) with multiple hierarchical codebooks. This approach allows fine‑grained discretization of latent representations and interleaves training between the encoder and tokenizer. Experiments show that BRIDLE achieves state‑of‑the‑art results on audio classification benchmarks and competitive performance on image and video classification tasks, outperforming traditional vector‑quantization methods.

AzeroS: Extending LLM to Speech with Self-Generated Instruction-Free Tuning

The paper introduces AZeroS, a speech‑adapted large language model that uses Self‑Generated Instruction‑Free Tuning (SIFT) to avoid task‑specific instruction data. By training only two lightweight projection modules on 25,000 hours of speech‑text pairs and 3,000 hours of paralinguistic labels, AZeroS achieves state‑of‑the‑art results on semantic and paralinguistic benchmarks while keeping the core LLM and audio encoder frozen.
