IR & Earnings Presentation Narration Guide: Balancing Accuracy, Neutrality, and Trust with Financial Pronunciation Rules

In IR and earnings videos, narration needs design more than performance

Narration for IR videos and earnings presentation videos is evaluated very differently from corporate branding or recruitment content. In investor-facing media, the top priority is not emotional impact but repeatable delivery without misunderstanding. The three essentials are accuracy, neutrality, and trust.

Accuracy means reading numbers, proper nouns, regulatory terms, and forward-looking statements exactly as intended. Neutrality means not sounding overly positive on favorable results or excessively dark on risk factors. Trust means creating the sense that the company is fulfilling its accountability through controlled delivery and clean audio.

In practice, it is not enough to simply receive a final script and record it. For IR projects, I always confirm at least these three items before recording:
1. Number-reading rules: millions, billions, bps, YoY, QoQ, and similar units
2. Proper-name pronunciation: titles, overseas locations, product names, subsidiaries
3. No-emphasis sections: forecasts, outlooks, risk statements, disclaimers

Without this preparation, revisions often appear late in post-production: “Please don’t stress that line,” or “That margin term is read differently in our internal materials.” In IR production, one narration revision can affect subtitles, on-screen graphics, and English translation. Good pre-recording design directly improves production efficiency.

Practical delivery rules to balance accuracy, neutrality, and trust

So how do you actually balance those three elements? In real projects, I rely on clear rules.

First, accuracy. Read numbers in meaningful chunks. For example, instead of mechanically reading every digit of a figure, structure the phrase by information units. In quarterly presentations, keeping one sentence within roughly 3.5 to 5.5 seconds helps synchronize narration with slide recognition.

Second, neutrality. In IR work, excessive pitch movement should be avoided. As a rule of thumb, reduce intonation by about 20 to 30 percent compared with commercial narration. End sentences decisively, but do not over-lift the tone. Do not sound cheerful in strong-performance sections. Likewise, do not become unnecessarily heavy in impairment or downward revision sections. Delivery should never sound like it is steering investment judgment.

Third, trust. This does not come simply from using a low voice. It is built through consistency:

• Keep sentence endings uniform
• Maintain stable pauses around punctuation
• Do not slow down awkwardly on technical terms

For Japanese IR narration, a speaking speed of about 270 to 320 characters per minute is generally practical. Too fast sounds light; too slow sounds uncertain.

As for audio, heavy compression or radio-style coloring is usually unnecessary. A light low-cut below 80Hz, avoiding too much boost around 2–4kHz, and a loudness target around -16 LUFS for voice-led videos or -18 LUFS when the BGM is denser will often produce a natural result. The goal is not “impressive sound,” but “sound that raises no doubt.”

Financial terminology should be standardized with a pronunciation sheet, not personal habit

The most common source of trouble in IR narration is inconsistency in financial term pronunciation. For example:

• EBITDA
• ROE
• ROIC
• CAGR
• Operating margin
• Profit attributable to owners of parent
• Impairment
• Amortization / depreciation
• Dilution
• Equity ratio

The key point is not “what is generally common,” but how that company standardizes it. It is very common for securities firms, IR agencies, PR teams, and finance departments to use different readings. That is why I recommend creating a pronunciation rule sheet in Excel or Google Sheets before recording, with at least these columns:
“Term / Pronunciation / Accent / First timecode / Approver / Notes”

I also recommend a special approach for forward-looking disclaimers such as statements explaining that forecasts are based on information available at the present time. These lines should be read 5 to 8 percent slower than the main body, with even less intonation. If read too quickly, they can sound glossed over, which weakens the compliance impression.

IR narration may look understated, but in reality it supports corporate accountability through sound. Standardized pronunciation, controlled emotion, accurate number handling, and disciplined audio quality—these four elements turn a video into something that is not only easy to follow, but credible. If you are producing an IR or earnings presentation video, do not select a narrator by voice alone. You should also ask whether they can design the read within a financial communication context.
