    <h2 id="abstract">1. Abstract<a name="abstract"></a></h2>
    <p> Text-to-Audio (TTA) generation is an emerging area within AI-generated content (AIGC), where audio is created
      from natural language descriptions. Despite growing interest, developing robust TTA models remains challenging due
      to the scarcity of well-labeled datasets and the prevalence of noisy or inaccurate captions in large-scale, weakly
      labeled corpora. To address these challenges, we propose CosyAudio, a novel framework that utilizes confidence
      scores and synthetic captions to enhance the quality of audio generation.
      CosyAudio consists of two core components: AudioCapTeller and an audio generator. AudioCapTeller generates
      synthetic captions for audio and provides confidence scores to evaluate their accuracy. The audio generator uses
      these synthetic captions and confidence scores to enable quality-aware audio generation. Additionally, we
      introduce a self-evolving training strategy that iteratively optimizes CosyAudio across both well-labeled and
      weakly-labeled datasets. Initially trained with well-labeled data, AudioCapTeller leverages its assessment
      capabilities on weakly-labeled datasets for high-quality filtering and reinforcement learning, which further
      improves its performance. The well-trained AudioCapTeller refines corpora by generating new captions and
      confidence scores, serving for the audio generator training.
      Extensive experiments on open-source datasets demonstrate that CosyAudio outperforms existing models in automated
      audio captioning, generates more faithful audio, and exhibits strong generalization across diverse scenarios.
