<h1>多模态内容生成技术</h1>
<br>
<p class='fst-italic mb-0'>YiwiseAI</p>
<p><b>一知智能</b></p>
<br>
</div>
<p>
研发了音频、文本、数字人（视频）等多模态内容生成技术。包括：</p>
<ul>
<li><b>百变音色</b><br>
可以将任意人音色的音频转换成“成千上万”不同音色的音频。</li>
<li><b>音色转换（柯南蝴蝶结）</b><br>
可以将任意人音色的音频转换成指定人音色的音频。
</li>
<li><b>基于大语言模型的 Text2SQL</b><br>
输入数据库的 schema 和查询问题，直接生成可执行的 SQL 语句。
</li>
<li><b>2D 数字人视频合成</b><br>
音频驱动的 2D 数字人视频合成，通过音频可以驱动数字人口型合成。
</li>
<li><b>小样本 TTS</b><br>
只需提供一段 3 秒的简短录音音频和你想合成的说话内容，即可快速合成你自己的 TTS 音频。

<h2 id="model-overview" style="text-align: center;">技术概述及场景</h2>
<br><br><br>
<h4 style="text-align: left;">百变音色</h4>
<p>
可以将任意人音色的音频转换成“成千上万”不同音色的音频。<br>
该项技术可以用来批量合成大量相同内容不同音色的音频（或视频）。同时，该项技术也可以去制作大量平行音色转换数据，为音色转换技术提供支持。
</p>
<br><br>
<h4 style="text-align: left;">音色转换</h4>
<p>
音色转换技术可以将任意人音色的音频转换成指定人音色的音频。<br>
我们的技术目前支持多种语种的音频的音色转换，同时支持流式语音转换（延迟 800ms）。<br>
可能应用到直播、短视频、影视制作等场景。可以合成特定人音色说不同语言，方言的音频。
</p>
<br><br>
<h4 style="text-align: left;">基于大语言模型的 Text2SQL</h4>
<p>
基于 BLOOM 预训练大语言模型，训练百亿参数级中文 Text2SQL 模型。<br>
在中文 Text2SQL 场景，达到了 ChatGPT 同等效果。
</p>
<br><br>
<h4 style="text-align: left;">2D 数字人视频合成</h4>
<p>
用户上传一段 5~10 分钟的拍摄视频，即可定制该人物形象的数字人模型。<br>
使用该模型可以批量合成大量数字人短视频。
</p>
<br><br>
<h4 style="text-align: left;">小样本TTS</h4>
<p>
基于 <a href='https://valle-demo.github.io/'>《Neural Codec Language Models are Zero-Shot Text to Speech Synthesizers》</a> 论文，我们在上万小时的中文音频数据上训练了中文小样本 TTS 模型。只需上传一段 3 秒及以上的个人音频片段，即可让该模型快速的合成你想要的特定人 TTS 音色。
