Key Insights: Built an AI-powered video creation and translation tool, improving transcription accuracy from 70% to 90–95% and saving educators an average of 13 hours per week.

About the Client

Guide Education is a collective of teachers, governors, technologists, and trainers supporting educational institutions through teacher training, staff development, consultancy, and online student support. With a large dataset of training materials in text format, they sought to transform them into inclusive, multilingual audiovisual resources.

The Challenge

Guide Education wanted to create short educational videos that could be easily translated into any language, reducing language barriers and fostering global inclusion in education.

They needed a solution that could handle:

• Accurate transcription of existing videos.
  
  
• High-quality translations into multiple languages.
  
  
• Regeneration of videos with translated audio and embedded subtitles.
  
  
• A user-friendly interface for live editing of transcripts and translations.
  

Marvik’s Approach

We developed an end-to-end AI platform combining speech-to-text, translation, and text-to-speech technologies.

Key capabilities included:

• Generating transcriptions from video content and translating them into any target language.
  
  
• Editing transcripts and translations in real time through a user-friendly interface.
  
  
• Recreating videos with translated audio and embedded subtitles for download.
  
  
• Using GANs and advanced ML techniques to ensure natural-sounding, accurate results.
  

The system was built collaboratively between our ML, backend, and frontend teams using Python, Golang, TensorFlow, Keras, PyTorch, MySQL, and GANs.

The Results & Impact

• Increased transcription accuracy from 70% to 90–95%.
  
  
• Enabled creation of multilingual educational videos at scale.
  
  
• Saved educators 13 hours per week on average, time that can be redirected to student engagement and outcome-focused activities.
