An assistant must carry an English condition such as “unless” through a Twi voice note, because it changes the action the speaker is asking for. If it drops that condition, a helpful-sounding reply can give the wrong instruction.
In 1970, NASA’s Apollo 13 crew faced a problem that could not be solved by treating each part in isolation. Carbon dioxide was building up in the Lunar Module. The available command-module canisters were square; the Lunar Module accepted round ones. At Mission Control in Houston, engineer Ed Smylie led the effort to create an adapter from materials already aboard. NASA’s Apollo 13 Flight Journal documents the problem and the improvised solution.
The condition was everything: use what is already on the spacecraft, make the square canister work with the round opening, and do it before the crew’s air became unsafe. Remove one constraint and you no longer have the same task.
“Unless” changes the instruction
A family voice note might begin in Twi, switch to English for one word, then return to Twi:
“Ka kyerɛ Auntie sɛ ɔntua deposit no nnɛ, unless landlord no agye ato hɔ sɛ ɔbɛtwɛn.”
The word “unless” sets the boundary. Tell Auntie to pay the deposit today, except if the landlord has confirmed they will wait.
An assistant that hears only “deposit,” “today,” and “landlord” may produce a neat reply that misses the point. The message is conditional. The landlord’s confirmation determines what happens next.
This is why code-switching needs more than recognising individual Twi and English words. The assistant has to hold the meaning of the whole sentence while the language changes around it.
Conditions often arrive in the middle
People do not always speak in clean, one-language instructions. A voice note can change direction halfway through:
“Please send the reference number to Kwame, but mma ɔmfa nkɔ bank no unless meka akyerɛ wo sɛ payment no aba.”
The request has two separate actions. Send Kwame the reference number. Do not let him take it to the bank unless the speaker confirms that payment has arrived.
That distinction matters around rent, school fees, a clinic appointment, or a family contribution. A condition may be one English word inside a longer Twi sentence, but it can carry the full decision.
Nkomo is built for natural Twi and Ghanaian English conversation, typed or spoken. You can hold to speak, interrupt naturally, and hear a reply. The useful reply should preserve the condition plainly: “Send Kwame the reference number, but tell him not to go to the bank until you confirm the payment has arrived.”
Restate the condition before acting on it
For instructions with money, timing, health, travel, or another person’s next step, ask the assistant to repeat the condition back. A short confirmation catches the error before it becomes a forwarded message or a rushed phone call.
Try wording like:
- “What must happen before she pays?”
- “Separate what I should do now from what must wait.”
- “Rewrite this message, but keep the ‘unless’ condition.”
That small habit makes the hidden logic visible. It also gives the speaker a chance to correct a name, amount, or condition while the conversation is still private and close at hand.
This is especially useful when you are deciding whether a voice note should reach the cloud. Nkomo asks for cloud consent clearly: never, ask each time, or this session. Its history stays on your device unless you choose otherwise, and turning history off purges it immediately. For a sensitive conditional message, that control belongs in the conversation, not buried after it.
A reply should show its working
Apollo 13’s adapter succeeded because the team kept the constraints in view. The square canister did not become round. The solution accounted for the mismatch.
A Twi and English assistant should do the same with language. It should not flatten “unless” into a general reminder, or turn a conditional request into an unconditional instruction. A good reply makes the dependency clear enough that the person listening can hear what happens now, what waits, and what event changes the plan.
