Supported Languages for Transcription and Translation

​
Which languages are supported for transcription?

CoLoop currently supports over 100 languages with near-human quality (more detail available here). If you’re transcribing online qual files When transcribing these files in CoLoop you should click detect language if there are multiple languages present in the online qual upload.

​
Which languages are supported for translation?

We currently support non-English to English translation of any language. Transcripts do not need to be translated in order to conduct analysis, however quotes and transcripts will be shown in the native language. Always transcribe files in their source language before translating to English. Ex: A focus group in Spanish must be transcribed first in Spanish, then translate to English.

​
What if my language is supported for translation but not transcription?

  • Translation within CoLoop can also be applied to txt and docx files.
  • If you are working in a language we support for translation but not transcription, you can upload 3rd party transcripts in the native language and translate them in CoLoop.
  • Be sure to checkout our formatting guides to ensure your native language transcripts are properly processed (more details here).

​
Simultaneous Translation

Simtrans files are supported by CoLoop in two ways. If you only have the simultaneously translated file, information about who is speaking and their role in the conversation is lost, which can adversely affect analysis. For best results, upload both the original audio/video in tandem with the simtrans file to have CoLoop diarize with more context and decode who is speaking. Screen Recording 2026 02 06 At 4 27 49 PM From ‘Import files,’ select Audio or Video (SimTrans), where you’ll need both the original and translated video. Once you upload both files, transcribe in the original language and input the number of speakers expected. You won’t be able to bulk upload multiple files, but you can bulk transcribe once they are all completed and contain the same number of speakers/language. CoLoop will use the original audio for speaker boundaries/identities, and the translated version will be kept as an additional layer so you can toggle between both languages. All analysis will be conducted using the original language. If you are conducting Non-English language studies you can also follow the guidelines below:
  • Transcribing and analysing in the native language if possible - you’ll be able to generate an English translation for any non-English files and will be able to toggle between languages at all times.
  • Asking your SimTran service to provide transcripts with labelled speakers
SimTrans files can be uploaded to CoLoop but please consider the following.
  1. Theme counts may not be accurate particularly if the interview involved more than 2 speakers
  2. CoLoop will not be able to as accurately distinguish moderator and participant statements so you will see moderator highlighted in the evidence panel
  3. These can be effectively used for simple use cases like summaries and finding quotes
