Prepare for Any Meeting or Event in Minutes

You have an important meeting tomorrow. The agenda is full of client names, product terms, and technical vocabulary that generic speech-to-text will get wrong. Normally, you’d spend time manually adding each term to the dictionary one by one — or worse, you’d skip it and deal with messy transcripts after. Vocabulary Builder lets you skip all of that. Upload the meeting agenda, slide deck, speaker list, or any relevant PDF — and AI automatically extracts the terms most likely to be misrecognized, generates the correction variants, and adds them to your dictionary in bulk. What used to take an hour of manual preparation now takes a few minutes.

​

When to use it

• Before a multilingual conference — upload the speaker list and program PDF to get names and session titles right
• Before an investor or client meeting — upload the earnings report or proposal to catch financial terms, product names, and people’s names
• Before a technical workshop — upload the spec document or training materials to handle industry jargon
• When joining a new project — paste meeting notes from previous sessions to learn the team’s vocabulary fast
• Before a product demo — upload the feature documentation so product names and technical terms appear correctly in live captions

​

How big is the difference?

Here’s a real example. We spoke this sentence during a live VoicePing session — once without preparation, and once after uploading a single PDF through Vocabulary Builder:

“On a non-GAAP basis, we filed the Form 10-Q with updated Llama 4.1 performance metrics.”

GAAP (an accounting standard) was misheard as GOP (a political party). One wrong word made the entire Japanese translation nonsensical. One PDF upload fixed it — no manual dictionary work required.

Step-by-Step: Preparing for a Meeting with a Real Document

Let’s walk through the full process using Meta’s Q2 2025 earnings call transcript — a real PDF full of product names, executive names, and financial terminology. The same workflow applies to any document in any language.

​

1. Open Vocabulary Builder

Open the Dictionary from any of these entry points, then select the Vocabulary Builder tab: Once the modal opens, select My Dictionary or Workspace Dictionary at the top — this determines where extracted phrases will be saved. Then select the Vocabulary Builder tab.

​

2. Upload Your Document

Select the language that matches your document, then upload it. You can drag and drop files or click to browse. Enter a session name if you want — otherwise one is generated automatically. We uploaded Meta’s earnings call PDF and clicked Create & Upload. You can also switch to the Enter Text tab and paste text directly (up to 50,000 characters) instead of uploading a file. File Limits:

​

3. Wait for AI to Analyze

After uploading, the session appears in the session dropdown with an “in progress” label and a percentage. Click on it to see the full progress bar. This may take several minutes depending on the file size. You can close the modal and come back later — processing continues in the background. Click + Create to start another session while this one is still running.

​

4. Review What AI Found

Once processing completes, the results appear. From the Meta earnings call PDF, Vocabulary Builder extracted 14 terms that speech-to-text is likely to get wrong — including executive names, financial terms, and product names: For each term, the AI has already generated:

• Special Word — the correct spelling
• Pronunciation — how it sounds when spoken
• Misrecognized Words — the incorrect transcriptions VoicePing should auto-correct

You can edit any of these, remove variants that don’t apply, click AI suggest for more variants, or uncheck terms you don’t need.

​

5. Save to Your Dictionary

Once you’re satisfied with the list, click Review X in My Dictionary (or Review X in Workspace Dictionary). This takes you to the Special Words Recognition tab where the phrases appear as a draft. Review them one more time, then click Save to apply. That’s it — from PDF upload to fully prepared dictionary in a few minutes. No manual entry, no guessing which terms might fail. The next time someone speaks these terms in a meeting, VoicePing gets them right.

​

The Difference It Makes

We spoke two sentences from the earnings call — once before uploading the PDF, and once after. Same speaker, same microphone, same VoicePing session. The only difference: a few minutes of preparation.

​

English Example 1: “Meta Quest” misheard as “met a Quest”

“Alexandr Wang from Scale AI asked about Llama 4.2 and Meta Quest 3S during the earnings call.”

“Meta” was misheard as “met a” — turning a product name into a random verb. The name Alexander was also corrected to Alexandr. Both fixes rippled into the Japanese translation, turning nonsense into an accurate sentence.

​

English Example 2: “GAAP” misheard as “GOP”

This is the example from the top of this page — GAAP (accounting standard) heard as GOP (political party), with the Japanese translation going from “non-Republican party” to the correct financial term. A few minutes of preparation prevented a completely wrong transcript.

​

Same Preparation, Different Language: Japanese Government Document

The same workflow applies to any language. We uploaded the Digital Agency’s (デジタル庁) Priority Plan PDF before a session about Japanese government digital policy. The document is dense with formal terminology that speech-to-text would normally mangle. Vocabulary Builder extracted 34 terms in minutes — including ガバメントクラウド, 防災デジタルプラットフォーム, 保活ワンストップサービス, IT 基本法, and クラウド第一原則. Manually building this list from scratch would have taken far longer.

​

Japanese Example 1: クラウド第一原則

「総務省報道資料によると、クラウド第一原則の適用が進んでいます。」

The dictionary corrected 第1 to the formal kanji 第一, and the English translation shifted from the awkward “Cloud’s first principle” to the accurate “cloud-first principle.”

​

Japanese Example 2: デジタル・ガバメント

「IT基本法に基づき、デジタル・ガバメントの推進を加速させます。」
