Overview

Who this competition fits

适合已有说话人确认/声纹识别实践经验的人,能处理16k单声道 WAV 音频,并自行准备训练数据与训练模型。也适合熟悉模型推理包部署和复现材料整理的团队;最终入围者需提交完整代码、权重和技术报告。

Read the original official blurb
在人工智能与语音技术迅猛发展的当下,声纹识别作为生物特征识别的重要分支,已广泛应用于金融安全、智能终端、个性化服务等领域。然而,当前主流声纹识别系统在面对儿童用户、同性干扰、远场使用、超短测试音频等复杂场景时,仍存在显著的技术瓶颈: Official track: 语音技术. Sponsor: 声网. Teams entered: 346.

Preparation

From registration to a first submission

  1. 01

    说话人确认

  2. 02

    声纹嵌入模型

  3. 03

    音频预处理与重采样

  4. 04

    PyTorch 推理部署

  5. 05

    NPZ 文件生成

  6. 06

    Docker/Linux 打包与 S3 上传

Before you commit: 难点不只是区分一对音频是否为同一人,而是要让同一套 embedding 在儿童注册、同性说话人、远近场和0.5秒/1秒超短测试音频等15个隐藏场景中都稳定工作。提交也有严格工程约束:只能输出统一维度的 embedding,并由余弦相似度完成验证,推理包的路径、NPZ字段和资源限制出错都会导致评分失败。
