## What is vTTS?

vTTS turns text and books into speech directly on your device, privately and offline.

• Import TXT, Markdown, HTML and RTF files
• Read Vietnamese text with or without tone marks, usernames and Unicode symbols
• Automatically continue to the next chapter
• Remember your current chapter and reading segment

Stay in control:
• Track progress by segment
• Seek to any position
• Highlight the segment currently being read
• Adjust reading speed from 0.5× to 1.5×
• Remember a different voice for each language
• Continue playback when switching apps or locking the screen

Export audio as:
• MP3
• WAV
• M4A
