Budget: $42

Multilingual Voice Recording Project

• Code-Switching Conversations

Project Name: BV Project Type: Remote | Ongoing (Limited Slots per Locale)

Project Overview Project BV is a multilingual speech data collection initiative designed to enhance Automatic Speech Recognition (ASR) systems for high-value multilingual call center scenarios, including financial services, healthcare, and telecommunications.

The project focuses on collecting natural code-switching conversational audio, where speakers alternate between two languages within a single conversational turn. Scripts will be provided; however, natural delivery, fluency, and context-appropriate language switching are essential.

Language Requirements Primary Language (Native level

• one required): Catalan (ca-ES: Spain)

Secondary Language (Required): Catalan or Basque

• Fluent

Participants may be located anywhere globally, provided they are native in Catalan (ca-ES: Spain) and fluent in English

The Project Manager will request language verification samples for both primary and secondary languages.

Participation Structure Participation is one-time only per speaker. Two speakers will form a pair (agent and customer roles). Speakers do not need to be in the same location. Scripts and recording instructions will be provided. Zoom is the preferred method for recording the conversations. Audacity is the preferred tool for converting audio files to the required sample rates and for verifying signal-to-noise ratio compliance.

Recording Scope Target volume: 200 hours of audio per locale Per pair output: 1.2 hours of recorded audio Quality acceptance: Minimum 80% usable speech hours

Compensation (USD
