Bring your own API keys, paste them once, and start translating speech. No markup on AI usage — you pay your providers directly.
Two kinds of key power the app — and they do different jobs. You connect them once; SpeechKey handles routing, recovery and playback.
Understand what's said and translate it. You need at least one engine key to begin.
Speak the translation aloud in a natural voice. Optional, but recommended for spoken output.
Every key is pay-as-you-go and billed by the provider — SpeechKey never touches your tokens. Grab one engine to start; add more for redundancy.
Everything BYOK lives in one place — engines and voices side by side.
Repeat for each engine and voice you want connected. Mix freely.
Keys are stored in the iOS Keychain — never on a SpeechKey server.
Pick the engine you trust most and the voice you like best. You can change either any time.
SpeechKey picks the fastest available provider per region and network — and switches mid-session if conditions change.
Automatically falls back to iFLYTEK on a domestic route when global providers are blocked or slow.
Real-time speech translation — point the mic at whoever is speaking and follow along. Not a two-way chat device; a layer that lets you understand what's being said.
The mic lights up and the status reads CONNECTED · LIVE.
Talk normally in any supported language — no turn-taking, no setup per person.
Words arrive as they're spoken, and are spoken back in your chosen voice.
For the resilient platform — routing, recovery, China mode and voice playback.
Token costs go straight to your providers. Monitor usage on each provider's own billing dashboard — SpeechKey never touches your tokens.
API keys are stored in the iOS Keychain and only ever leave the device toward the provider you chose.
Audio streams directly from your device to your chosen provider. No middleman server stores your speech.
Download SpeechKey, paste your keys, and start translating speech in minutes.
