01 · DEPLOYMENT
Three deployment options
From hosted API to on-prem — choose what your security review requires. Switching later is a settings change.
Private cloud
- Deployed in your cloud account and region
- All traffic stays inside your network
- You manage your own accounts and keys
On-prem
- The whole system runs on your hardware
- Audio never reaches the public internet
- Suitable for air-gapped requirements
02 · CUSTOMISATION
Subtitles customised to your style
Send us your existing subtitles and term list. We configure everything once — every job after that follows the same standard.
Subtitle style
Typeface, position, line count, colour, and script variant, all set to your existing spec. Separate profiles for different brands or channels.
Glossary
Product names, people, and case IDs go into the glossary so every transcript gets them right. Spoken-to-written conversion follows your editorial rules.
Your subtitles as reference
Provide subtitles you have already completed. New work follows your punctuation, line breaks, and tone — no more re-editing from scratch.
03 · USE CASES
Who uses it
For any team that handles large volumes of Cantonese recordings.
Media
Subtitle your entire catalogue
Shows, shorts, event replays. Line length, placement, and wording match your channel’s spec.
Contact centre
Turn call recordings into searchable text
Handles phone-quality audio and Cantonese mixed with English. Results connect directly to your QA system or CRM.
Education
Turn lectures and talks into text
Keep both a verbatim transcript and a written-Chinese version. Lecturer phrasing and course names go into the glossary.
Legal & compliance

06 · FAQ
Common questions
- Can it run entirely on our own systems?
- Yes. With on-prem deployment, transcription and storage all happen on your hardware, and audio never reaches the public internet. Private cloud and hosted API are also available — all three use the same engine.
- Will our audio be used to train models?
- No. Your recordings and content are never used to train models for other customers. Your glossary and style settings belong to you.
- What do you need to customise the subtitle style?
- Just your existing subtitle files (SRT or other formats) and a list of common terms. Once configured, every job follows the same standard automatically.
- What can the API do?
- Submit audio or video, check progress, and download subtitles and transcripts. Webhooks or batch processing can be added to fit your systems — we help set this up during onboarding.
- How does pricing work?
- By usage, not per seat. Private deployment and custom setup are one-time fees, billed separately from usage. Submit the form below with your monthly volume and we will provide a quote.
