About Speechly
Speechly is a developer platform for building real-time voice user interfaces — speech recognition engineered for live, streaming use inside apps rather than batch transcription after the fact. As users speak, Speechly returns words and extracted intents on the fly, enabling interfaces that react mid-sentence: search that filters as you talk, forms that fill while you dictate, voice moderation that flags in real time.
Its API combines low-latency streaming speech-to-text with natural-language understanding you configure for your domain, so "show me red shoes under fifty euros" arrives as structured intent, not just a transcript. SDKs cover web, iOS and Android. (Speechly was acquired by Roblox; standalone availability has narrowed — evaluate current access before committing, and consider alternatives like Deepgram for similar streaming needs.)
Strengths: genuinely real-time UX (streaming, partial results), built-in intent extraction, and voice-moderation capabilities that attracted gaming platforms. Weaknesses: post-acquisition, its future as an independent product is limited — new projects should verify current terms; it's developer tooling, not a consumer app.
Who it's for: developers exploring streaming voice UI patterns — with the caveat that its acquisition makes it a case study to learn from as much as a platform to adopt today.

Frequently Asked Questions
What is Speechly.io and how does it function as a dictation tool?
Speechly.io is a native macOS speech-to-text dictation application built to help professionals, agencies, and developers convert their spoken thoughts into polished text. Rather than serving as a standard, turn-taking virtual assistant or generating a raw, unrefined voice transcript, Speechly functions as a background copilot. Users simply hold down the spacebar to speak naturally across more than 150 compatible apps, and the underlying AI instantly converts that verbal stream into structured, usable writing.
How does Speechly.io refine raw audio into structured written formats?
The application goes beyond simple word-for-word voice typing by applying natural language understanding to your spoken sentences. It features a specialized "Email Mode" alongside various selectable formatting tones—such as professional, casual, friendly, assertive, or gentle. When you speak, the system automatically cuts out repetitive phrasing and awkward pauses, fixes grammatical errors, and transforms the raw dictation into a well-organized layout featuring natural greetings, clean paragraphs, and clear calls to action.
What are the differences between the platform's Cloud, Local, and Neural AI engines?
To balance speed, safety, and correctness, the application allows users to route their voice processing across three distinct AI execution layers:
Cloud Engine: Engineered for maximum processing speed, delivering ultra-low latencies (under 50 milliseconds) where words appear instantly as you speak.
Local Engine: Runs completely on your Mac's internal Apple Silicon neural hardware. It requires no active internet connection, providing total data confidentiality because your audio never leaves your physical device.
Neural & Neural Advanced Engines: Optimizes transcribing accuracy by using advanced deep-learning models that automatically pick up on your unique voice nuances, contextual industry acronyms, and custom vocabulary over time.

What platform ecosystems and applications does Speechly.io support?
Speechly.io is built using 100% native code optimized specifically for macOS systems (running cleanly on Apple Silicon M1, M2, and M3 chips). Because it runs globally at the system level, it integrates into your workflow without requiring you to constantly toggle back and forth between different browser tabs. It works seamlessly within standard business environments like Slack, Notion, Microsoft Outlook, Apple Notes, Gmail, and code editors.
What makes Speechly different from normal speech-to-text?
It streams results in real time as users speak — apps can react mid-sentence instead of waiting for the recording to finish.
Is Speechly still available?
Speechly was acquired by Roblox and standalone access has narrowed. Verify current availability; Deepgram and similar APIs cover comparable streaming use cases.
What was Speechly used for?
Voice search and filtering, hands-free form filling, and real-time voice chat moderation.
