Voice Input

To enable voice input for implementing in-app multi-person conversation functionality, follow the steps below:

**Step 1: Install Sound Card Service on the Server**

Ensure that the sound card service is installed on the server.

**Step 2: Enable Voice Service Authorization**

- Apply for an authorization code from the developer platform to ensure that voice service authorization is enabled.

- Obtain the authorization code provided by Pingxing Cloud Business. Contact Pingxing Cloud Merchant to enable voice service authorization.

- In the application backend editing section, allow the use of audio input functionality. If not authorized, this function will be invisible.

**Step 3: Check if the Rendering Server Allows Access to the Microphone**

Ensure that the rendering server allows the application to access the microphone. Access needs to be enabled as shown in the image below:

**Step 4: Set up HTTPS Environment or Use localhost**

- Set up an HTTPS environment or access the application using localhost.

- Find the microphone icon above the control ball in the bottom right corner of the application interface and click to allow microphone usage.

- This enables the use of audio input functionality for multi-person conversations and other related needs.

By following the above steps, you can successfully implement in-app multi-person conversation functionality and other voice input-related requirements.

**Note:**

- For local debugging, you can use OpenSSL to set up a free HTTPS environment. Below are brief steps for configuring HTTPS on Nginx and example commands for generating certificates (applicable to Windows and Linux systems).

### Example Commands for Generating Certificates using OpenSSL:

#### Generating Certificates on Windows:

```html
openssl genpkey -algorithm RSA -out mykey.pem -pkeyopt rsa_keygen_bits:2048
openssl req -new -x509 -days 3650 -key mykey.pem -out mycert.pem -subj "/C=US/ST=State/L=City/O=Organization/OU=Department/CN=CommonName"

```

#### Generating Certificates on Linux:

```html
openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits:2048
openssl req -new -x509 -key private_key.pem -out certificate.pem -days 365

```

#### Nginx Configuration for HTTPS:
```html
server {
    listen       {{port}} ssl;
    server_name localhost;
    ssl_certificate      /path/to/cert.pem;  # Certificate file path
    ssl_certificate_key  /path/to/key.pem;   # Private key file path
    ssl_session_cache shared:SSL:1m;
    ssl_session_timeout 5m;
    ssl_protocols SSLv2 SSLv3 TLSv1 TLSv1.2;
    ...
}
```

By following these steps, you can set up an HTTPS environment and enable audio input functionality for in-app multi-person conversations and other requirements.
