基础篇-ChatTTS介绍

ChatTTS 文本转语音项目在github爆火出圈，引来大家极大的关注。短短2周左右的时间，在 GitHub 上已经斩获了23.5k的Star量。ChatTTS是专门为对话场景设计的文本转语音模型，例如LLM助手对话任务。它支持英文和中文两种语言。

作者本人也在 x (原推特)上表示，ChatTTS 突破了开源天花板。不过，目前开源的只是底模，没有经过 SFT 监督微调。其具有下面特点:

1.   对话式 TTS: ChatTTS针对对话式任务进行了优化，实现了自然流畅的语音合成，同时支持多说话人。

2.   细粒度控制: 该模型能够预测和控制细粒度的韵律特征，包括笑声、停顿和插入词等。

3.   更好的韵律: ChatTTS在韵律方面超越了大部分开源TTS模型。同时提供预训练模型，支持进一步的研究。

下面我将给大家实操ChatTTS的效果展示。

实操篇: 编写利用ChatTTS实现中文文本转语音

配置对应的运行环境

from IPython.display import clear_output
!git clone https://github.com/2noise/ChatTTS
%cd ChatTTS
!pip install -r requirements.txt
!pip install openai==1.30.1
!pip install pynini==2.1.5 Cython   WeTextProcessing torchaudio
clear_output()

下载模型权重

import ChatTTS
import torch

torch.set_float32_matmul_precision('high')
from IPython.display import Audio

chat = ChatTTS.Chat()
chat.load_models()

进行模型推理实现中文文本转语音

进阶篇:ChatTTS教程-固定音色

在ChatTTS中，控制音色的主要是通过参数spk_emb来传递对应的音色。

chat = ChatTTS.Chat()
speaker  = chat.sample_random_speaker() 
params_infer_code = {
  'prompt':'[speed_2]',
  'temperature':.1,
  'spk_emb' : speaker}

其中sample_random_speaker对应的函数:

def sample_random_speaker(self, ):
  dim = self.pretrain_models['gpt'].gpt.layers[0].mlp.gate_proj.in_features
  # dim=768
  std, mean = self.pretrain_models['spk_stat'].chunk(2)
  # std.size:(768),mean.size(768)
  return torch.randn(dim, device=std.device) * std + mean

可以看出最终返回的音色向量，是通过将随机生成的正态分布值缩放和偏移得到的，其分布特性由spk_stat模型定义的标准差和均值决定。

通过拆分句子和合并音频来实现超长语音

%%time 
my_text="""你跑得快，22岁有个家，身边全是赞叹。
你跑得慢，30岁还在路上追求梦想。
有的人为了车房拼了一辈子，有些人买辆摩托车走遍大好河山。
你想成为怎样的人，过怎样的生活，只要你不后悔就行。
有的人喜欢狼吞虎咽，有的人喜欢细嚼慢咽，允许别人做别人，也允许自己做自己，一岁有一岁的味道，跟着自己的心就好。
不是所有选择都必须要做出正确的选项的，只要你想，你可以选择你喜欢的选项。
人生没有白读的书，也没有白走的路。
沉默的时光叫做扎根。沿途的花会一直开，以后的路也是，祝你也祝我。"""
