开源语音合成模型SparkTTS使用

一、环境配置

复制代码

git clone https://github.com/SparkAudio/Spark-TTS.git

pip install -r requirements.txt

二、模型下载

从modelscope进行下载，pip install modelscope

创建一个download.py

复制代码

import torch

from modelscope import snapshot_download

snapshot_download("SparkAudio/Spark-TTS-0.5B", local_dir="SparkAudio/Spark-TTS-0.5B")

执行python download.py进行下载。

三、使用

在example文件夹下能够看到infer脚本文件，

复制代码

# Get the absolute path of the script's directory
script_dir=$(dirname "$(realpath "$0")")

# Get the root directory
root_dir=$(dirname "$script_dir")

# Set default parameters
device=0
save_dir='example/results'
model_dir="pretrained_models/Spark-TTS-0.5B"
text="身临其境，换新体验。塑造开源语音合成新范式，让智能语音更自然。"
prompt_text="吃燕窝就选燕之屋，本节目由26年专注高品质燕窝的燕之屋冠名播出。豆奶牛奶换着喝，营养更均衡，本节目由豆本豆豆奶特约播出。"
prompt_speech_path="example/prompt_audio.wav"

# Change directory to the root directory
cd "$root_dir" || exit

source sparktts/utils/parse_options.sh

# Run inference
python -m cli.inference \
    --text "${text}" \
    --device "${device}" \
    --save_dir "${save_dir}" \
    --model_dir "${model_dir}" \
    --prompt_text "${prompt_text}" \
    --prompt_speech_path "${prompt_speech_path}"

运行

复制代码

bash infer.sh

能够成功合成语音，参数所表示的意思对应如下：

text 需要克隆语音所对应的文本

device 指定显卡编号

save_dir 克隆语音的保存路径

model_dir 大模型的保存路径

prompt_text 样本语音的文本信息

prompt_speech_path 样本语音的保存路径

复制代码

python -m cli.inference \
    --text "你好" \
    --device 0 \
    --save_dir "result" \
    --model_dir pretrained_models/Spark-TTS-0.5B \
    --prompt_text "吃燕窝就选燕之屋，本节目由26年专注高品质燕窝的燕之屋冠名播出。豆奶牛奶换着喝，营养更均衡，本节目由豆本豆豆奶特约播出。" \
    --prompt_speech_path "example/prompt_audio.wav"

如果想要改变声音的性别，音调，速度，可以在infer.sh中看到对于这些参数的说明，但是这几个参数要一起加才能用，否则会报错
