Phone calling
Call a real phone number from the web app. You bring your own
Twilio account and pay
Twilio directly for the minutes — MacroLang never holds call credit and never bills you per minute.
Supported destinations: Canada/US, Vietnam, Philippines.
Your Auth Token is not stored. It is used once, right here, to create a revocable API Key on your account — then discarded. Only that key is kept, encrypted. Revoke it anytime in Twilio without touching your account.
Calls are not translated yet — that needs live audio processing and is coming later.

Not linked
Use a local/geographic number if you can — international carriers often reject or rewrite toll-free caller ID.
Reading
Theme
Same set as the phone app
Caption language
The language every caption is rendered in for you
Prefer romanized captions
Show Latin script alongside native script for CJK/Thai/Myanmar/Khmer/Lao
On-device romanization model
Real phonetic romanization (not just accent-stripping) for Chinese/Japanese/Korean/Thai/Burmese/Khmer/Tagalog/Indonesian/Turkish/Spanish/Vietnamese. No Cebuano, Ilocano, Malay, or Lao model exists upstream. Runs in your browser — no server, no key. ~41 MB one-time download.
Audio & video
Microphone
Which input MacroLang listens to.
Speaker
Where call audio comes out.
Noise suppression
Cuts steady background noise — fans, traffic, room hum.
Echo cancellation
Stops your speaker feeding back into your mic. Two speakerphones in one room still echo — that is physics, not this switch.
Push to talk
Hold Space to speak; the mic is closed otherwise.
Camera on when joining
Start room calls with video already on.
Receiving box
A small floating window showing the person you called, with you in the corner.
Feedback button
The small Feedback control in the corner. Turn it back on if you dismissed it.
Server voices
Prefer a female voice
Used wherever one exists. Ten languages have none on the server — those try your device's voice instead.
Voice & translation
Speaking
Speaking language
The language you talk or type in
Translation style
Natural
Smooth, everyday phrasing so the meaning lands cleanly.
Literal
Adds a word-for-word line with notes, so you can see how the other language actually builds the phrase. Sits under Natural.
Gloss intensity
How often the literal line appears.

Speech recognition
Engine
Offline SenseVoice runs on-device — works in any browser and covers Asian languages better.
Listen source
Mic is your microphone. Tab shares a Chrome tab or screen (tick Share audio). Cable is a VB-Audio / Voicemeeter loopback so other apps can be captioned.
Detect spoken language automatically
Switches between your speaking language and the languages of the people in the call, so a mixed table doesn't have to pick one first. Only switches on sustained evidence, never mid-sentence. Works between languages that share a script — the recogniser only ever listens in one language at a time, so it cannot hear that you have switched from English to Thai until you tell it. Tap the language badge on your live line to correct a wrong guess. Turn this off if you always speak one language.
Other languages I read
If someone speaks one of these, you get their words untouched instead of a translation — no delay, no engine error. Best first.
Safe Mode Macro++
Masks profanity in the captions you read (f***). Off by default on every tier — MacroLang shows what was actually said, and softening it silently is a translation bug, not politeness. The translation itself is never altered, so turning this off restores the exact text with no new request.
Hearing (TTS)
Speak captions aloud
The browser reads incoming captions in your caption language
Voice engine
Browser uses your OS voices. Kokoro is on-device Apache-2.0. Server uses Piper (MIT) then gTTS.

Motion
Ambient field
A slow digital swell behind the app, rippling where you click. Pauses itself during calls so it never competes with video.

Messages & channels
Their language on top
Show what the other person actually said as the main line, with your language underneath. Off puts your language first.
Channel join & leave sounds
A short, quiet blip when you join or leave a voice channel — much softer than Discord's.
Demo call
Simulated two-way call for trying captions without another person. Lives here, not on the chat screen.
Appearance Macro+
Themes and interface density.
Privacy
What we keep, what we never keep, and who else sees it.
API keys
Optional extras — translation is free for everyone, forever. Google, MyMemory, Lingva, Apertium, LibreTranslate and offline Argos need no key and are never gated. A key here only adds that provider as one more engine choice. Keys are stored in this browser only. They are never uploaded to MacroLang, never saved on our servers, and never shared with another user or another device — they are attached to your own translation request and sent nowhere else. Clearing this browser's site data erases them.
