Terms of Service

Voice Bridge, Rwanda Media Voice Bridge Platform

The agreement between you and Duka Labs that governs your use of the Voice Bridge platform.

By creating an account on Voice Bridge, you confirm that you have read, understood, and agree to be bound by these Terms of Service.

If you are using Voice Bridge on behalf of an organisation, you confirm that you have authority to bind that organisation to these Terms.

If you do not agree to these Terms, do not create an account or use the platform.

1. The Service

Voice Bridge is an AI-powered subtitling and transcription platform operated by Duka Labs Limited in its capacity as Implementing Consultant for the Rwanda Media Voice Bridge (RMVB) project. The platform provides:

• Automated transcription of audio and video content, with a focus on Kinyarwanda and English.
• Subtitle generation with timecodes in SRT and compatible formats.
• A browser-based editing interface for reviewing, correcting, and adjusting subtitle outputs.
• Translation assistance between Kinyarwanda and English (with French and Swahili to follow).
• Export to standard post-production formats for use in Premiere Pro, DaVinci Resolve, Frame.io, and similar tools.

AI Accuracy Limitation, Please Read

Voice Bridge uses AI models that produce draft outputs. They are not perfect. Current performance: approximately 8 errors per 100 words for Kinyarwanda; approximately 3 errors per 100 words for English. Performance varies with background noise, overlapping speakers, and code-switching between languages.

You are responsible for reviewing and correcting all outputs before using them in final published, broadcast, or submitted content. Duka Labs does not warrant that outputs are error-free and accepts no liability for losses arising from uncorrected AI-generated errors in final content.

2. Accounts and Registration

• You must provide accurate and complete information when creating an account and keep it updated.
• Each account is for use by one individual or one organisation. Do not share your login credentials.
• You are responsible for all activity that occurs under your account.
• Notify us immediately at security@voicebridge.rw if you become aware of any unauthorised access to your account.
• We may suspend or terminate accounts that violate these Terms, without prior notice where the violation is serious.
• Minimum age: you must be at least 18 years old to create an account.

• The content does not infringe the intellectual property rights of any third party under Rwanda Law No. 055/2024 or any other applicable law.

4.4 Ownership of outputs

AI-generated subtitles, transcriptions, and translations produced from your content are jointly owned by the platform and you, in accordance with the IP framework established under the RMVB project and Rwanda Law No. 055/2024.
