🗣️ Voice Selection

After selecting a language, you'll be able to choose from the available voices for that language. Voices differ in tone, accent, and gender. For example, you might prefer a softer voice for storytelling or a neutral tone for professional narration.

🎧 Audio Format

Choose the output format for your audio file. Each format serves different use cases based on quality, size, and compatibility.

• WAV (Waveform Audio File Format):
  Uncompressed, high-fidelity audio. Best for editing, mastering, or professional applications where quality is critical. Larger file size.
• MP3 (MPEG Audio Layer III):
  Compressed audio with good quality and small file size. Suitable for web use, sharing, streaming, and mobile apps. Universally supported.
• AAC (Advanced Audio Coding):
  A modern audio codec that delivers better sound quality than MP3 at similar or smaller sizes. Used in platforms like YouTube, iOS, and Android.

Tip: Choose WAV for quality, MP3 for compatibility, and AAC for efficient mobile use.

⏩ Speech Speed

Adjust the playback speed of the generated voice:

• 0.5x – 0.9x: Slower speech, suitable for language learners or clarity-focused narration.
• 1.0x (Default): Natural, balanced pace ideal for most uses.
• 1.1x – 4.0x: Faster delivery for rapid consumption or shorter audio length.

Use the speed slider to test what pace works best for your audience or content type.
