Voice acting projects range from short commercial spots to lengthy audiobooks. Understanding how much recording time you need helps with scheduling studio sessions and budgeting costs. This calculator estimates the total time to record your script using a simple formula:
Where is the total time in minutes, is the word count, is the actor's reading speed in words per minute, and is a multiplier to account for retakes and pacing adjustments.
While this calculation is straightforward, many real-world factors influence session length. Professional voice actors often require multiple takes to capture the right tone, and unexpected pauses or dialogue changes can add minutes or hours. By adjusting the multiplier, you can experiment with conservative or aggressive estimates.
The average English speaker reads aloud at about 150 words per minute. Trained voice actors might speak faster or slower depending on the project. Table 1 provides a few example speeds and the resulting time for a 1,000-word script using a multiplier of 1.2:
| Speed (wpm) | Estimated Minutes |
|---|---|
| 120 | 10 |
| 150 | 8 |
| 180 | 7 |
These times cover only the raw vocal performance. You should also factor in rest breaks, equipment setup, and any direction from a producer. Larger projects, such as multi-character audiobooks, require even more overhead for rehearsals and quality checks.
Script length is the primary driver of recording time. A script with 10,000 words can easily take several hours to record, especially if there are complex character voices or emotional scenes that require multiple takes. Breaking the script into smaller chunks is a common strategy for longer works. Each session focuses on a manageable portion, reducing fatigue and improving consistency.
If you're unsure of your script's word count, many text editors provide this information. For translation projects, keep in mind that the word count may change between languages, affecting how long the recording will take. Translators sometimes expand or contract the script to match the timing of on-screen visuals, especially in dubbing.
The retake multiplier is a catch-all for unexpected delays. Some performers might nail every line in one or two takes, while others require more. Complex technical or medical terminology often needs additional tries to achieve clear pronunciation. The presence of a director can also extend sessions as they provide feedback and request alternate deliveries. Set a higher multiplier if you're new to voice acting or expect many revisions from the creative team.
For example, a 5,000-word e-learning script with a speaking speed of 140 words per minute and a multiplier of 1.5 would require:
minutes.
From there, you might schedule a two-hour session to allow time for warm-ups, breaks, and unforeseen changes.
Recording can be physically demanding. Vocal fatigue, dry mouth, and simple restlessness all take a toll on performance. A comfortable studio or home booth with good acoustics makes a difference. Frequent short breaks keep energy levels consistent. Consider additional buffer time for calibrating equipment such as microphones and preamps or adjusting soundproofing panels.
If you're renting studio space, include setup and teardown time in your estimate. Studio rates may be billed by the hour, so an accurate forecast prevents overbooking or running out of time before the session wraps.
The time spent recording is only one part of a voice acting project. Post-production includes editing breaths, removing mistakes, and adding effects. If you're handling editing yourself, budget at least the same amount of time as the raw session, often more. Professional audio editors use specialized software to clean and process files, sometimes doubling or tripling the total time needed before the final product is ready.
When contracting with an editor, discuss their expectations upfront. Knowing the estimated recording length helps them schedule their workflow and provide an accurate quote. If the project involves mixing with background music or sound effects, factor that into the overall timeline as well.
Many voice actors collaborate remotely, sending files to producers or clients via cloud storage. In this scenario, communication delays can affect project time. Some teams prefer to record live over conferencing software so directors can offer immediate feedback. This approach often streamlines the process but requires additional planning around time zones and internet stability.
When scheduling remote sessions, share your availability windows and confirm that all participants have adequate equipment and network bandwidth. Technical issues can quickly add minutes or hours to a recording day. Have backup plans for file transfers, such as alternative upload services, to avoid losing time to connection problems.
A soft-spoken narrator for an audiobook might have a slower delivery than a high-energy video game character. Different genres call for different pacing, so adjust the reading speed to match the style. If you're voicing multiple characters, consider how quickly you can switch between them without losing consistency. Some actors practice each voice individually, while others record all lines for one character before moving to the next.
Rehearsal time is also part of the equation. Even if you're comfortable with the script, reading through it aloud once or twice before hitting record can prevent mistakes and speed up the session. Add this rehearsal time to your multiplier if you plan a thorough run-through before capturing each segment.
Estimating project time is essential for both hobbyists and professionals. It ensures you can secure studio space, meet client deadlines, and set realistic expectations for collaborators. This calculator offers a transparent approach. By inputting script length, reading speed, and retake multiplier, you can experiment with different scenarios and adjust for the inevitable surprises that arise in recording.
Moreover, clear communication about schedule expectations helps maintain good relationships with clients and crew. Producers appreciate accurate forecasts when booking engineers, editors, or additional actors. Even in a home studio, understanding the time commitment allows you to plan around other responsibilities, preventing last-minute rushes and ensuring a high-quality final product.
Use a realistic reading speed based on your previous projects or practice sessions. Choose a multiplier that reflects your experience level, the complexity of the script, and the number of takes you anticipate. Finally, remember to include breaks, setup time, and editing in your overall schedule. With these considerations, you'll approach each project with confidence and a clear plan.
