自然语音 2 - Pytorch（正在开发中）

在 Pytorch 中实现自然语音 2、零样本语音和歌唱合成器

NaturalSpeech 2 是一个 TTS 系统，它利用具有连续潜在向量的神经音频编解码器和具有非自回归生成的潜在扩散模型来实现自然和零样本的文本到语音合成

该存储库将使用去噪扩散而不是基于分数的 SDE，并且也可能提供阐明的版本。它还将在适用的情况下对注意力/变压器组件进行改进。

安装

$ pip install naturalspeech2-pytorch

用法

 import torch
from naturalspeech2_pytorch import (
    EncodecWrapper ,
    Model ,
    NaturalSpeech2
)

# use encodec as an example

codec = EncodecWrapper ()

model = Model (
    dim = 128 ,
    depth = 6
)

# natural speech diffusion model

diffusion = NaturalSpeech2 (
    model = model ,
    codec = codec ,
    timesteps = 1000
). cuda ()

# mock raw audio data

raw_audio = torch . randn ( 4 , 327680 ). cuda ()

loss = diffusion ( raw_audio )
loss . backward ()

# do the above in a loop for a lot of raw audio data...
# then you can sample from your generative model as so

generated_audio = diffusion . sample ( length = 1024 ) # (1, 327680)

有调理

前任。

 import torch
from naturalspeech2_pytorch import (
    EncodecWrapper ,
    Model ,
    NaturalSpeech2 ,
    SpeechPromptEncoder
)

# use encodec as an example

codec = EncodecWrapper ()

model = Model (
    dim = 128 ,
    depth = 6 ,
    dim_prompt = 512 ,
    cond_drop_prob = 0.25 ,                  # dropout prompt conditioning with this probability, for classifier free guidance
    condition_on_prompt = True
)

# natural speech diffusion model

diffusion = NaturalSpeech2 (
    model = model ,
    codec = codec ,
    timesteps = 1000
)

# mock raw audio data

raw_audio = torch . randn ( 4 , 327680 )
prompt = torch . randn ( 4 , 32768 )               # they randomly excised a range on the audio for the prompt during training, eventually will take care of this auto-magically

text = torch . randint ( 0 , 100 , ( 4 , 100 ))
text_lens = torch . tensor ([ 100 , 50 , 80 , 100 ])

# forwards and backwards

loss = diffusion (
    audio = raw_audio ,
    text = text ,
    text_lens = text_lens ,
    prompt = prompt
)

loss . backward ()

# after much training

generated_audio = diffusion . sample (
    length = 1024 ,
    text = text ,
    prompt = prompt
) # (1, 327680)

或者，如果您希望Trainer类负责训练和采样循环，只需简单地执行

 from naturalspeech2_pytorch import Trainer

trainer = Trainer (
    diffusion_model = diffusion ,     # diffusion model + codec from above
    folder = '/path/to/speech' ,
    train_batch_size = 16 ,
    gradient_accumulate_every = 2 ,
)

trainer . train ()
