### Start Server using ngrok

Source: https://github.com/w-okada/voice-changer/blob/master/Realtime_Voice_Changer_on_Colab.ipynb

This code block starts the voice changer server and exposes it via ngrok. It requires users to provide their ngrok authentication token. The first run may involve downloading models, which can take 1-2 minutes. Users can optionally select a region for ngrok and choose whether to clear the console.

```python
# @title Start Server **using ngrok**
# @markdown This cell will start the server, the first time that you run it will download the models, so it can take a while (~1-2 minutes)

# @markdown ---
# @markdown You'll need a ngrok account, but <font color=green>**it's free**</font> and easy to create!
# @markdown ---
# @markdown **1** - Create a <font color=green>**free**</font> account at [ngrok](https://dashboard.ngrok.com/signup) or **login with Google/Github account**
# @markdown **2** - If you didn't logged in with Google/Github, you will need to **verify your e-mail**!
# @markdown **3** - Click [this link](https://dashboard.ngrok.com/get-started/your-authtoken) to get your auth token, and place it here:
Token = '' # @param {type:"string"}
# @markdown **4** - *(optional)* Change to a region near to you or keep at United States if increase latency
# @markdown `Default Region: us - United States (Ohio)`
Region = "us - United States (Ohio)" # @param ["ap - Asia/Pacific (Singapore)", "au - Australia (Sydney)","eu - Europe (Frankfurt)", "in - India (Mumbai)","jp - Japan (Tokyo)","sa - South America (Sao Paulo)", "us - United States (Ohio)"]

#@markdown **5** - *(optional)* Other options:

ClearConsole = True  # @param {type:"boolean"}

# ---------------------------------
# DO NOT TOUCH ANYTHING DOWN BELOW!
