### How to Use the Text-to-Speech App:
1. **Enter Text**:
   - Type or paste the text you want to convert to speech in the main text area.
   
2. **Select Language**:
   - Choose the language of the input text. The available language options include:
     - 🇺🇸 American English (`a`)
     - 🇬🇧 British English (`b`)
     - 🇪🇸 Spanish (`e`)
     - 🇫🇷 French (`f`)
     - 🇮🇳 Hindi (`h`)
     - 🇮🇹 Italian (`i`)
     - 🇧🇷 Brazilian Portuguese (`p`)
     - 🇨🇳 Mandarin Chinese (`z`)
     - 🇯🇵 Japanese (`j`)
3. **Select Voice**:
   - Choose the voice you want for the speech. There are multiple voice styles based on tone and gender (e.g., af_heart, af_joy, etc.).
   
4. **Adjust Speech Speed**:
   - Use the slider to adjust how fast the speech will be generated. The speed can be set from 0.5x to 2.0x, with 1.0x being the default normal speed.
5. **Generate Speech**:
   - Once you've selected the text, language, voice, and speed, click the **"Generate Audio"** button. The app will process the text and generate the speech.
6. **Download Audio**:
   - After the audio is generated, you can play it directly within the app or download it as a .wav file by clicking the **"Download Audio"** button.
### Additional Features:
- **Text Translation**:
   - If you enter text in another language and want to hear it in English, provide your OpenAI API key (optional).
   - The app will automatically translate the text to English and generate the speech in English with the voice you selected. 
- Enjoy exploring different languages, voices, and speeds with the text-to-speech conversion!
