Carryover: Phone Calls You Can See

Many of the 50+ million Americans with hearing loss can't make a phone call alone. Today's relay services put a human operator in the middle, and in FCC-commissioned MITRE tests human-typed captions lagged 4.8 to 6.8 seconds behind speech. Carryover joins an ordinary call, so the other side can be any phone: a pharmacy, a clinic, a bank. It speaks for you with a spoken disclosure, you read the other person as live captions, and whatever you type is said word for word. You pick how much it does alone. Relay only speaks your words. Assist also presses menu keys, waits on hold, flashes the screen when a person picks up and answers routine questions from facts you chose to share. Auto also works toward a goal you set. When asked for something you didn't share, it says "one moment" and asks you on screen instead of guessing. After the call you get a summary, the commitments made and the transcript. Your profile stays on your device. The AssemblyAI Voice Agent API is the agent's ears and mouth, with our own Relay Brain plugged in as a bring-your-own LLM. For each turn the Brain picks your words verbatim, silence, or a model reply, and every reply sentence passes a fabrication gate written in code that blocks any date, ID or number about you that you didn't share. Tool calls press keys, ask you and end the call. Universal-3.5 Pro Realtime streaming produces the captions, with speaker labels that catch transfers and key terms from your profile. A second Voice Agent session plays the reps of five simulated businesses. Try it with no account: a sample call, live calls to simulated businesses, or a practice line where your own phone becomes the pharmacy. It is backed by 856 automated tests. A graded evaluation with hidden answer keys found zero fabrications, and when the bank asked for a member ID the user never shared, Carryover asked instead of guessing. It is not FCC-certified, and calls to real phone numbers are designed but not shipped in this build.
