Kofi’s pesticide question. His family’s safety depends on six gates.

Before a farmer hears AgriVoice, six gates must pass: an accountable cocoa-sector partner, reviewed spoken Asante Twi, agronomist-approved chemical guidance, working WhatsApp delivery, real farmer-speech evaluation, and a complete staff safety rehearsal. Each gate has evidence and a pass or fail result; none can be replaced by a launch date.

Imagine Kofi, a composite cocoa farmer, standing beneath a corrugated roof after an afternoon in the field. He holds his phone close and asks in Twi when it is safe to return after spraying. Rain is gathering, and he needs to decide whether his family can enter the plot the next morning.

A confident but unverified answer could expose someone to pesticide residue. Silence could leave Kofi relying on a guess. Until AgriVoice can respond with reviewed guidance or route the question to a named person, Kofi should hear neither a product demo nor an improvised answer.

Gate 1: A partner must own the pilot and its escalations

A cocoa-sector partner must agree to recruit the 20 to 50 farmers in the two-week pilot. That partner must also name the extension officer who receives questions AgriVoice cannot answer safely.

“Partner interested” does not pass this gate. There needs to be an accountable institution, a defined farmer cohort, and a person responsible for the escalation queue.

This matters most when the system encounters an ambiguous recording, an out-of-domain question, or missing reviewed content. The technology can recognize uncertainty and stop. It cannot visit a farm, inspect a crop, or accept responsibility for advice. The extension officer closes that gap.

For Kofi, this gate determines whether his difficult pesticide question reaches a person or sits unresolved while tomorrow morning approaches.

Gate 2: Every approved answer must be reviewed in spoken Asante Twi

AgriVoice has 37 owner-approved content blocks that require spoken Asante Twi from a farming-aware translator. The translation must sound natural when read aloud and preserve cocoa vocabulary, safety qualifications, and the original agronomic meaning.

Machine translation cannot provide the final wording. In testing, “kokoo,” meaning cocoa, returned as “chicken.” The sentence could still sound fluent while giving advice about the wrong subject.

The translator therefore works against locked English source text. If the English appears wrong, the translator raises a query instead of quietly rewriting the advice. Each completed block needs review before it can become something a farmer hears.

Pass means all 37 approved blocks contain reviewed, speakable Asante Twi. One empty or unresolved block remains a known place where the system may select an answer and have nothing safe to say.

Gate 3: A Ghanaian agronomist must clear the chemical guidance

Three chemical blocks remain held because essential details are missing. A Ghanaian agronomist must explicitly verify dosage, re-entry intervals, and pre-harvest intervals before those blocks can be released.

Until then, AgriVoice refuses chemical questions. That refusal is a safety control working as designed.

This is the hardest moment in Kofi’s scene. His question sounds straightforward, and the pressure to give a useful answer is strong. Yet a product name without verified instructions is incomplete advice. If the agronomist has not cleared the relevant block, the system must escalate rather than fill the gap with plausible language.

Pass means an accountable agronomist has reviewed the three blocks and either approved corrected guidance or kept them withheld. Approval cannot be inferred from general expertise or copied from an unverified label summary.

Gate 4: WhatsApp must work end to end

A healthy Meta app must have WhatsApp attached, the required messaging and management permissions, and a System User token that does not expire overnight. Then a real inbound and outbound message must succeed.

Dashboard status alone does not count. A green indicator cannot prove that a farmer’s audio reaches AgriVoice, receives the right response, and returns through WhatsApp.

The current phone connection and webhook path have recovered from earlier access restrictions, but the practical test still matters before exposure: send a real message through the complete route and confirm the reply arrives.

Pass means the exact channel farmers will use has completed that round trip.

Gate 5: Real farmer speech must be measured

At least 20 real farmer questions must be recorded and transcribed before the pilot. These recordings create the field evaluation set for Twi speech recognition.

Read speech collected in a quiet room cannot reveal every failure found beside a road, under a metal roof, or among code-switched cocoa terms. The existing speech-recognition baseline has performed well on read speech, but the release decision needs farmer voices in realistic conditions.

Consent and deletion behavior must also be tested. Farmers need to know what is recorded, why it is retained, and how it can be removed.

Pass means the team has 20 or more consented questions with reliable transcripts, measured recognition results, and tested deletion behavior. A collection of audio files without consent records or reference transcripts does not qualify.

Gate 6: Staff must rehearse the complete safety path

Before Kofi ever sends his question, staff must run the full application and try to break it. The rehearsal covers ordinary cocoa questions, ambiguous requests, pesticide questions, irrelevant topics, poor transcripts, and cases requiring more than one reviewed block.

No unsafe answer may reach the test user. Missing or uncertain answers must escalate successfully, and someone must confirm that the named extension officer can receive and handle them.

This is the turn in Kofi’s story. With the six gates passed, his question no longer forces a choice between confident invention and silence. AgriVoice can select reviewed guidance when it exists. When it does not, the question moves to the accountable person before advice is given.

The next morning, Kofi’s phone contains either a reviewed Asante Twi response he can understand or a clear notice that a person is handling the question. The checklist earns that ordinary moment.
