About the role
AIxBlock is recruiting native speakers for the sample stage of Juniper: natural bilingual conversations that switch between a native language and fluent English. Each participant works alongside a conversation partner and may contribute up to one hour of recorded speech.
Speak mostly in your native language (85–90%), with natural, occasional switching into English (10–15%). Conversations must be unscripted: no reading, rehearsed lines or AI-generated speech.
Use assigned everyday topics, such as daily routines, work or study, travel, technology, health and wellness, shopping, or general opinions. Speak naturally, as you would with a friend.
Target language pairs: German–English, French–English, Spanish–English, Italian–English, Japanese–English, Vietnamese–English and Chinese–English. AIxBlock will contact applicants whose profiles suit the project.
Scope of Work
- Record a natural conversation with a partner on the assigned everyday topic.
- Maintain approximately 85–90% native-language speech and 10–15% English.
