Description by Xiang Gui Written by the developer, not by AppBrain. Click to read.
Echo: Semantic Voice Keyboard reimagines productivity by turning your voice into text with remarkable accuracy. Powered by advanced speech recognition and semantic language models, it understands context to correct homophones, fix punctuation, and provide fluid, natural input.

KEY FEATURES:
• Real-time streaming transcription — see your words appear as you speak
• Stream & Batch modes — real-time or high-accuracy transcription, your choice
• In-keyboard settings panel — switch AI modes without leaving your conversation
• Four AI modes: Quick transcript, Polish, Concise, and full Rewrite
• Smart homophone correction powered by deep decode technology
• Bilingual support (Chinese & English) with seamless switching
• Integrated keyboard extension — dictate anywhere across iOS
• Context-aware corrections using conversation history
• Personalized dictionary that learns your vocabulary
• Built-in translation and structured output formatting

HOW IT WORKS:
Echo uses cloud-based speech recognition to deliver fast, accurate transcription. An optional AI editing layer polishes your text — fixing errors, removing filler words, and refining your writing style. You control how much editing is applied.

PRIVACY:
Audio is processed via secure cloud speech recognition services. Text corrections use encrypted API connections. No audio is stored on our servers. No data is shared for advertising. Your transcription history stays on your device.

Whether you're drafting messages, taking notes, or writing emails, Echo transforms how you interact with text. Speak naturally — Echo handles the rest.
