## Checksub

Checksub is a video localization platform built around subtitles. You upload a video, and the service automatically transcribes the speech, generates synchronized captions in the original language, and lets you restyle or animate them with dozens of presets — including one-click karaoke effects. From that base transcription it can then translate the whole script into more than 200 languages, keeping the timing and line breaks appropriate for on-screen reading rather than a raw machine translation.

Beyond subtitles, Checksub handles AI dubbing: it isolates the original voices from music and background noise, then regenerates the dialogue with realistic AI voices while preserving the rest of the audio atmosphere. Voice cloning lets you substitute a cloned version of your own voice in some 30 languages, and a script-to-subtitle mode converts an existing written script into perfectly synchronized captions without transcription errors.

Everything is editable in an online editor, so once the AI has produced subtitles or a dub you can rewrite, re-time, regenerate individual sentences, and export either burned-in video or subtitle files. The platform is aimed at training departments, social media teams, YouTubers and agencies that need to publish the same content in many languages without re-shooting.

**Pricing & Plans:** Checksub offers a free trial that includes credits covering roughly one hour of video and access to every feature. Ongoing use is on paid subscription plans; exact tiers and per-minute limits are shown on the Checksub pricing page, and larger teams can book a demo for custom quotes.

- **Automatic subtitling and animation:** Generates accurate captions with AI, then lets you apply dozens of style presets and animations, including one-click karaoke effects, before exporting burned-in video or subtitle files.
- **Translation into 200+ languages:** Machine translation built specifically for subtitles, so line lengths and timing stay readable instead of copying a generic document translator.
- **AI dubbing with voice isolation:** Separates music and background noise from the original voices, then replaces only the speech with realistic AI dubbing so the audio atmosphere is preserved.
- **Voice cloning in 30 languages:** Clone a speaker's voice from a sample and use it to replace the original voice-over across dozens of languages with a natural delivery.
- **Advanced online editor:** Edit, re-time and regenerate any subtitle line or dubbed sentence directly in the browser, with script-to-subtitle alignment for pre-written content.

**Strengths:** Subtitle, translation, dubbing and voice cloning live in one workspace; Purpose-built subtitle translation keeps line lengths readable; Voice isolation preserves music and ambient audio in dubs; Free trial credits cover about an hour of video, enough to test real workflows

**Limitations:** Credits are consumed per language created, which adds up for multi-market projects; The free trial is short-lived and paid plans are subscription-based; The editor has many options, so new users need some time to learn the interface

## SyncWords

SyncWords is language infrastructure for live media. A broadcaster or event producer sends one audio or video feed, and SyncWords returns the same content in the form each audience needs: same-language captions for accessibility, translated subtitles for audiences who read another language, and AI voice dubbing for viewers who would rather listen than read. The company positions itself as a layer that sits alongside the streaming stack you already run, rather than a replacement for it.

The product line maps to how media is actually delivered. SyncWords Live handles broadcast and streaming captioning and can put captions directly into a live stream from the cloud without re-encoding video or installing caption hardware — around half a second to the video and under two seconds to the captions. Events targets meetings and conferences with a branded caption URL and QR code produced in under a minute, so attendees read captions on their own phones while house displays and confidence monitors show the same page. VOD Express automates captions, subtitles and dubbing for recorded files.

Pricing is usage-based. The site lists pay-as-you-go live AI captioning at around $30 per hour, with effective rates dropping as annual committed volume grows — from $27/hour at 60 hours a year down to $9/hour at 9,000 hours. Usage is counted in hours per language and per output, which matters when one programme needs several subtitle tracks. Standard support is included, and Broadcast and Enterprise agreements add uptime SLAs, 24/7 monitoring and a dedicated success manager.

**Pricing & Plans:** Usage-based paid pricing. Live AI captioning is listed at $30 per hour pay-as-you-go; pre-paid annual packages drop the effective rate from $27/hour (60 hours/year) to $9/hour (9,000 hours/year, most popular). Usage is charged per language and per output. Custom quotes available for enterprise volumes; trial sessions available on request.

- **Live captions from the cloud:** Send your existing SRT/MPEG-TS, CMAF or RTMP stream and get captions back in under two seconds without re-encoding video or adding caption hardware.
- **Custom dictionaries and ASR accuracy:** Human-verified accuracy keeps live captions fast and correct, with custom dictionaries for presenter names, players, places and specialist terms.
- **Multi-language subtitles and translation:** Deliver same-language captions, translated subtitles and AI dubbing from one feed, so a single broadcast reaches every market in its own language.
- **Vocalics AI voice dubbing:** Vocalics AI voice dubbing recreates the speaker's tone and pacing in another language, suitable for live news, sports, events and live shopping.
- **Integrations and Live API:** Works with AWS Elemental, Brightcove, Dacast, LinkedIn Live, Vimeo, YouTube, PheedLoop and other platforms, with a Live API for custom pipelines.
- **Events with QR code and embed:** Events users can start a session and get a branded URL and QR code in under a minute, with captions on attendee phones and confidence monitors.

**Strengths:** Delivers captions, translated subtitles and AI dubbing from one pipeline; Can insert live captions without re-encoding video or adding hardware; Transparent published hourly rates that drop with committed volume; Strong integration story across AWS Elemental, Brightcove, Vimeo and YouTube

**Limitations:** Commitment-based annual pricing puts the best rates out of reach for small teams; Custom quotes are required before you know your real cost; Atmospheric preservation in AI dubbing is good but not studio-perfect for every accent; Charges are per language and per output, so multilingual runs add up quickly
