It cannot be denied that the influence of Microsoft Azure in the TTS(text-to-speech text-to-speech) segment of artificial intelligence is dominant, just as ChatGPT is in the NLP field as it can do whatever it wants. Don't you see that almost all Douyin marketing accounts use Microsoft's speech synthesis technology, and its influence can be seen from this. The only flaw is that the price is slightly higher, although it can also be used in China. iFLYTEK Speech Synthesis Replacement, but we only want the best one. This time we use the free open source library edge-tts to realize the text-to-speech operation and grab the wool of Microsoft edge.
TTS text-to-speech basic usage
First install the edge-tts library:
pip3 install edge-tts
After the installation is successful, run the edge-tts command directly on the terminal:
edge-tts
The help menu is displayed to indicate a successful installation:

It can be seen at a glance that almost all mainstream lingua francas are supported. The Gender field is the gender of the synthesized voice, Male means male, Female means female, and characters starting with zh are Chinese voice characters. Here is an example of Xiaoyi from Microsoft:
edge-tts --voice zh-CN-XiaoyiNeural --text "Hello, I am a smart voice assistant" --write-media hello_in_cn.mp3
The meaning of this command is to use the zh-CN-XiaoyiNeural character to synthesize the voice: "Hello, I am a smart voice assistant", and then write the audio stream to the hello\_in\_cn.mp3 file.
The program returns:
Downloads edge-tts --voice zh-CN-XiaoyiNeural --text "Hello, I am a smart voice assistant" --write-media hello_in_cn.mp3 WEBVTT 00:00:00.100 --> 00:00:00.525 Hello 00:00:00.525 --> 00:00:00.912 ah 00:00:01.050 --> 00:00:01.238 I 00:00:01.238 --> 00:00:01.375 yes 00:00:01.387 --> 00:00:01.700 intelligent 00:00:01.700 --> 00:00:02.050 voice 00:00:02.062 --> 00:00:02.550 assistant
The program will automatically output the time axis and voice text, so that even subtitle files are available, which can be said to kill two birds with one stone and kill two birds with one stone.
At the same time, we can also adjust the speech rate of the synthesized speech:
edge-tts --rate=-50% --voice zh-CN-XiaoyiNeural --text "Hello, I am a smart voice assistant" --write-media hello_in_cn.mp3
The --rate parameter can speed up or slow down the speech rate of the synthesized speech synchronously through the plus or minus sign.
Alternatively, adjust the volume of synthesized speech:
edge-tts --volume=-50% --voice zh-CN-XiaoyiNeural --text "Hello, I am a smart voice assistant" --write-media hello_in_cn.mp3
The --volume parameter can adjust the volume of the voice.
Unfortunately, and The official speech synthesis library of Microsoft Azure In contrast, the open source speech synthesis library does not support voice tuning based on markup language (SSML), such as intonation and emotion adjustment, but this is free after all, and the requirements should not be too high.
Python Script Speech Synthesis
In addition to speech synthesis through commands, edge-tts also supports Python scripts, edit the test.py file:
import asyncio
import edge_tts
TEXT = "Hello, I am a smart voice assistant, Xiaoyi"
VOICE = "zh-CN-XiaoyiNeural"
OUTPUT_FILE = "/Users/liuyue/Downloads/test.mp3"
async def _main() -> None:
communicate = edge_tts.Communicate(TEXT, VOICE)
await communicate.save(OUTPUT_FILE)
if __name__ == "__main__":
asyncio.run(_main())Here we directly call the save method of the communicate instance through the asynchronous mode, and the audio files of speech synthesis can be generated concurrently and asynchronously, which is very convenient.
It is also possible to automatically find the language we need through the voice management library:
import asyncio
import random
import edge_tts
from edge_tts import VoicesManager
TEXT = "Chinese Speech Test"
OUTPUT_FILE ="china.mp3"
async def _main() -> None:
voices = await VoicesManager.create()
voice = voices.find(Gender="Female", Language="zh")
communicate = edge_tts.Communicate(TEXT, random.choice(voice)["Name"])
await communicate.save(OUTPUT_FILE)
if __name__ == "__main__":
asyncio.run(_main())Here, the built-in VoicesManager library is used to randomly select Chinese voice characters to complete the speech synthesis operation.
In addition, voice streams and letters can also be generated synchronously through scripts:
import asyncio
import edge_tts
TEXT = "Here is the voice stream test"
VOICE = "zh-CN-XiaoyiNeural"
OUTPUT_FILE = "test.mp3"
WEBVTT_FILE = "test.vtt"
async def _main() -> None:
communicate = edge_tts.Communicate(TEXT, VOICE)
submaker = edge_tts.SubMaker()
with open(OUTPUT_FILE, "wb") as file:
async for chunk in communicate.stream():
if chunk["type"] == "audio":
file.write(chunk["data"])
elif chunk["type"] == "WordBoundary":
submaker.create_sub((chunk["offset"], chunk["duration"]), chunk["text"])
with open(WEBVTT_FILE, "w", encoding="utf-8") as file:
file.write(submaker.generate_subs())
if __name__ == "__main__":
asyncio.run(_main())After this asynchronous call, the audio will be written to test.mp3, and the subtitle file will be written to test.vtt. Later, the generated subtitle file can be superimposed on the video through ffmpeg, please refer to: Based on Python3(Autosub) and Ffmpeg with GoogleTranslation (Google Translate) to achieve bilingual subtitles (verbatim) for your videos
epilogue
The open source speech synthesis edge-tts library can improve the efficiency of speech synthesis, and greatly reduce the threshold of speech synthesis, paving the way for automated video editing. In the future, it will be combined with the AI drawing framework based on the Stable-Diffusion algorithm, and artificial intelligence AI one-click drawing The one-stop service of dubbing, dubbing and subtitles is just around the corner.
