How to train an AI voice bot to answer like your best sales rep

A real estate agency calls its old database, and clients object, interrupt and ask unexpected questions. That is why it pays to know how to train an AI voice bot: an untrained one names the price too early, promises a discount that doesn't exist and goes in circles. You can't call the same client a second time, and the minutes are already paid for.

“Training AI” is a tab of the bot card that teaches the bot to answer the way your best manager would. You don't need to write prompts: you correct the reply in plain words right in the test chat, and the AI writes the rule into the instruction itself. The bot learns in days, not in weeks of call agent training.

Watch the two-and-a-half-minute video, and below you will find step-by-step setup.

Why train your AI voice bot

• Online school: auto-training practises the objections “too expensive”, “I'll think about it” and “send it by email”. The bot answers with specifics and leads to booking a consultation.
• Services, lawyers, renovation: you upload your price list and answers to frequently asked questions. The bot stops making up prices and timelines.
• B2B sales: a review of real calls shows the phrase where clients are lost. The fix goes straight into the instruction.
• Clinics and salons: manual training is enough for a receptionist bot. It confirms and reschedules appointments without unnecessary selling.
• Recruitment: the bot calls candidates from their CVs and books a call with a recruiter. Train it to say a polite goodbye if the person isn't looking for a job: extra questions only annoy the candidate.
• Head of sales: the “Virtual Head of Sales” (AI acting as the head of the sales department) reviews dialogs and calls instead of them.

Three AI voice bot training modes

The “Training AI” tab opens a window with three modes:

• “Manual training” — you lead the dialog yourself and edit the instruction with the “Fix” button;
• “Automatic training” — the AI plays clients and the head of sales, runs the dialogs and edits the instruction on its own;
• “AI training on real calls” — the AI reviews the bot's real calls in full.

All edits go into the same instruction as on the “Instruction” tab; to see how it is structured, read “AI voice bot script”. The “Save” button in the bottom panel saves the edits.

How to fix a bot reply in the test chat

1. 1
   Start a dialog

   Open “Training AI” → “Manual training” → “Start training”. The bot greets you with its starting phrase, just like on a real call.
2. 2
   Write as a client

   In the “Type a message...” field or by voice, until the bot answers incorrectly.
3. 3
   Click “Fix”

   Under the bad reply. The “Fix the reply” window opens.
4. 4
   Describe the fix in three steps

   The situation, what not to do, what to do. For example: “If the client asks about the price before describing their task, do not name the price right away; first clarify the task.” Write in general terms, without direct speech. The bot would quote a ready-made phrase word for word, and its speech would sound wooden.
5. 5
   Check “Before / After”

   Click “Change”. The AI picks the instruction block itself and shows the “What changed in the instruction” window. “Apply” keeps the edit and reruns the dialog, “Undo” cancels it.
6. 6
   Save

   Click “Save” in the bottom panel, or the edits will be lost on reload.

Not sure why the bot answered that way? Click “Ask a question”: the AI names the rule that fired and suggests a fix. Your earlier comments are kept in the “— Select saved text —” list in this browser. To check an edit from scratch rather than on the replayed dialog, click “New chat”.

Also try to “break” the bot with the questions heard most often on cold calls: “Who is this?”, “What services?”, “How much does it cost?”, “That won't work in our industry.” The bot will answer even an unplanned question — unlike a keyword robot, it won't break. But the answer will be average: the bot may reveal the purpose of the call too early or claim you don't do something you actually do. Also catch phrases that sound unnatural, such as “I have information that may interest you”, and repetitions: when the client repeats the same objection, the bot should answer in different words. Fix each such reply with “Fix” and check it in a “New chat”.

How to check that the bot answers consistently: “Debug mode”

Sometimes the bot answers correctly in the chat but says something quite different on a call. The AI composes every reply anew, and a vague rule produces one variant one time and another the next. That is why one good reply in a test doesn't prove the bot is trained.

1. 1
   Tick the box

   “Debug mode” under the message field.
2. 2
   Type a client line

   It is sent 10 times with a one-second pause. A progress line shows which of the 10 requests is running.
3. 3
   Compare the variants

   Identical replies are hidden, and only the different ones stay in the feed. The summary line shows how many unique variants were found.
4. 4
   Fix the bad variant

   Click “Fix” under it, clarify the rule and send the line again.

Variants that differ by a couple of words are fine. Variants that differ in meaning show the rule is ambiguous, and on calls the bot will answer differently each time. A line in this mode costs as much as 10 ordinary ones, so turn it on at key moments: price, objections, booking. A reply after a dynamic database is checked with the “Check answer stability” link under it (more in “AI voice bot knowledge base”).

How long to train an AI voice bot: rounds of 100 calls

Training is not a one-time setup but rounds of 100 calls: launch, listen, fix the replies and start a new round. For a cold database, it is convenient to run the first round in auto-training on synthetic data — and the AI will also help you come up with entry points, that is, reasons for the call. A bot for incoming calls needs a couple of days of training, seven at most: you still won't foresee about 10% of real-life wording in tests. Only automate a script that has already worked in practice.

The method and timelines by scenario are in “AI voice bot for business”, section “How to launch the bot so it brings results”.

How to upload a price list, a script and FAQ answers to the bot

The “Fix the prompt” button opens the “Main instruction update” window. Paste your price list, sales script or answers to frequently asked questions and write the task. For example: “Rewrite the instruction so that the bot answers about prices strictly according to the price list below.” Click “Fix the prompt” in this window, check “Before / After”, untick the edits you don't need and click “Apply”.

Large and frequently changing data — free slots, addresses, properties — is better connected as a dynamic database rather than written into the instruction (more in “AI voice bot knowledge base”). The bot requests only what it needs and does not mix up dates and addresses. You can connect it yourself with a developer or order turnkey implementation: the button is at the end of the article.

Automatic AI voice bot training

Automatic training is training on synthetic data: the AI plays the clients, and the selected check evaluates the bot's replies. Choose a direction — “Outgoing” and/or “Incoming”. In the “What to practise” list, choose a client type (sceptic, neutral, warm, difficult) or a case: “too expensive”, “are you a robot?”, “I'll think about it”, a secretary and reaching the decision maker, a refusal. By default, it runs 10 dialogs per direction.

Ways to check the replies:

• “Virtual Head of Sales” rates the replies through the eyes of a strong salesperson;
• “Instruction compliance” catches made-up facts and skipped plan steps;
• “My own check prompt” checks against your criteria; you can take a ready-made template.

For the first run, choose “Confirm each save”, later “Auto save”: then you don't have to watch the run. The approximate time and cost are shown in the window before the start.

Training an AI voice bot on real calls

The “AI training on real calls” mode takes conversations from the last 7 days. Set the period, “Maximum calls per run” and “Minimum client lines in a call” — 3–5 for live conversations. The check is “Virtual Head of Sales” or a template, for example “Where the conversation fell apart”.

For a weak call, the window “The check found a flaw — fix the instruction?” opens. You can apply the fix, rewrite it by hand or skip the call. This mode is noticeably cheaper than auto-training: the AI does not play clients in it.

The “Find a call” button finds a call a client complained about. Paste the ID from the call details for the last 7 days and click “Open the call” — the conversation loads into the chat for fixing. A loaded call also shows the webhooks: what the bot received before the conversation, what the dynamic database returned and what was sent after the call. How to review them is covered in “AI voice bot knowledge base”.
