eSpeak TTS - Text to Speech

eSpeak TTS - Text to Speech is a highly responsive synthesizer.
Designed to be a fully functional TTS backend for Android smartphones and tablets, it is incredibly lightweight and supports over 100+ languages.
Whether you use screen readers like TalkBack or any other screen reader, or simply need a reliable text reader, this app delivers uncompromising performance with ultra-low latency.
🚀 KEY FEATURES & HIGHLIGHTS:
1. 🌍 Trilingual Support & Voice Variants:
• Designed specifically for multilingual users. You can configure Primary, Secondary, and Tertiary languages at the same time.
• Intelligent Voice Switching: Assign different voices for different languages. The engine automatically detects and switches voices instantly while reading mixed-language text.
• Rich Voice Variants: Choose from over 100+ built-in eSpeak voice variants (Male, Female, Whisper, Robotic, Klatt, etc.) for each language to suit your preference.
2. 🔢 Advanced Number & Pause Processing:
We understand that screen reader users need precise control over numbers. We provide dedicated formatting options:
• Reading Styles: Read numbers as Single Digits (1-2-3), Pairs (12-34), Triplets (123-456), or Full Words.
• Pause Options: Add a small pause between each digit, pair, or triplet. Perfect for seamlessly reading OTPs, phone numbers, and IDs.
• Smart Thresholds: Set custom rules (e.g., "Apply mode only if the number has more than 6 digits").
3. 🔤 Custom Dictionary & Text Filtering:
• Custom Dictionary: Complete control over pronunciation. Add any word you want the engine to read correctly, or mute specific words you want it to skip.
• Unicode Normalization: Accurately reads a wide range of special Unicode characters and stylized text.
• Emoji & SSML: Toggle emoji reading on/off. The engine also supports basic SSML tags for advanced text processing.
4. 🎛️ Complete Prosody & Audio Control:
• Volume & Sound Boost: Adjust independent volume levels. Need even louder speech? Turn on the Sound Boost feature to instantly increase the reading volume.
• Advanced Equalizer & Presets: Fine-tune voice tones using built-in presets (Bass Boost, Treble/Clarity, Vocal Bright, Warm, Night Mode) or a 5-band Custom Equalizer.
• Auto-Clarity Feature: Automatically adds extra treble presence as speech speed increases, ensuring absolute clarity even at high rates.
• Punctuation Control: Choose to read all punctuation, no punctuation, or specify only the custom punctuation marks you need.
• Speed, Pitch & Inflection: Fine-tune speaking rate, pitch, and voice fluctuation (inflection) for a natural or robotic tone.
5. 👁️ Accessible App UI & Themes:
• High Contrast Mode: The app interface includes Light, Dark, and a special High Contrast theme tailored for low-vision users.
6. 🔒 Privacy & App Stability:
• Local Speech Processing: All text-to-speech synthesis and custom dictionary processes happen strictly and safely on your device. Your speech data is never sent to any external server.
• Crash Reporting: To help us improve the app and fix technical bugs quickly, the app uses Firebase to collect strictly anonymous crash logs (requires internet connection).
