The demand for accessible, fast, and scalable multimedia content continues to accelerate. Across industries, teams are managing growing volumes of video, training, and marketing assets, while expectations for accessibility, localization, and delivery speed rise in parallel.

Manual captioning workflows are no longer sustainable at scale. To address this, WellSaid has introduced two new capabilities designed to remove post-production barriers and advance content workflows.

Caption Files in Studio and Word Timing through the API provide immediate access to accurate, time-coded transcripts and captions alongside every generated voice clip. Both features help enterprises accelerate production, maintain compliance standards, and deliver high-quality content across media channels.

For organizations where speed, precision, and accessibility are critical to business, these capabilities represent a new standard in voice production.

The challenge with manual captioning at scale

Manual creation of SRT and VTT files introduces avoidable complexity and delays into the production cycle.

Every caption file that requires manual formatting, timestamping, and syncing adds operational overhead. For teams producing content at scale, the cost is measured in lost efficiency and increased exposure to accessibility compliance risks under regulations such as ADA and WCAG.

Additional post-processing to align transcripts with video, animation, or interactive learning assets compounds these challenges. Workflows become fragmented, timelines stretch, and resources are diverted away from higher-value initiatives.

Integrated captioning and synchronization are essential to keeping production efficient, compliant, and scalable.

Caption Files in Studio: Fast, integrated subtitles for every clip

Captioning is now fully integrated into the Studio workflow. With Caption Files, users can export SRT and VTT files directly alongside their audio clips, eliminating the need for separate transcription tools or manual formatting.

This built-in capability supports ADA and WCAG compliance while enabling teams to move from production to launch faster.

Real-world benefits include:

• Streamlining multimedia production: Content creators and video editors can export caption-ready files for platforms like YouTube, LMS systems, and internal portals, eliminating the need for additional editing steps.
• Expanding content reach: Educators and trainers can deliver accessible learning experiences that meet institutional standards, improving learner engagement and compliance.
• Maximizing content value: Podcasters and marketers can repurpose interviews, soundbites, and promotional clips across websites, social media, and global campaigns with captions built in.

How to download caption files in Studio

Caption Files fit directly into your existing Studio workflow.

To download Caption Files:

1. Select the completed clip from your Studio project
2. Click the Download button in the toolbar or from the clip card
3. Toggle Captions on
4. Select SRT, VTT, or both formats
5. Download the audio and caption files together

Teams managing high volumes of content can automate caption inclusion:

• Navigate to Account > Settings
• Enable Global Download
• Select preferred caption formats for all future downloads

Caption Files are available to Business and Enterprise customers. To activate this feature, contact your WellSaid account manager.

Word Timing via API: Advanced audio synchronization

For developers and technical teams, precise synchronization between audio and visual elements is critical. Word Timing delivers detailed metadata alongside every generated voice clip, providing exact timestamps for each spoken word.

This feature automates audio-text synchronization, supporting faster development cycles and eliminating the need for manual post-processing.

With Word Timing, teams can:

• Automate caption generation: Generate subtitle files and time-coded transcripts directly from the API without separate workflows.
• Build dynamic, interactive experiences; Power word-by-word highlighting, interactive learning modules, and real-time accessibility features.
• Create lifelike media; Synchronize speech with avatars, character animations, and lip-sync movements for gaming, e-learning, and entertainment applications.

How it works:

Each API response provides a ZIP package containing:

• The generated audio file
• JSON metadata with exact word-level timestamps
• Optional SRT and VTT caption files

Word Timing is available to all free and paid API users. No plan changes are required.
