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 – Per Pair, 2 Speakers) All rates below are paid in United States Dollars (USD) and apply to one hour of final audio (30 minutes per speaker).

Hello, This project aims to collect multilingual voice recordings to improve ASR systems for call centers, specifically focusing on natural code-switching between Brazilian Portuguese and English. Ensuring high-quality audio recordings that meet the specified standards is crucial for the project's success, particularly maintaining that 80% usability threshold for the collected data. I have participated in similar projects that required gathering and processing voice data, ensuring clarity and adherence to quality standards. My experience in working with audio recording tools and understanding the nuances of language will help meet the project requirements. I can assist in providing guidance on effective recording techniques and audio processing to achieve the desired outcomes. For this project, I would implement a structured approach: - Initial briefing to confirm understanding of the scripts and recording setup. - Coordination of recording sessions to ensure a quiet environment and optimal audio quality. - Post-recording review to ensure adherence to quality standards and provide feedback. Could you clarify how many participants are expected to contribute from each locale? - Are there specific scripts you would prefer for the recordings? - Is there a timeline for when you expect to start collecting the audio? Sincerely, Moh Harianto
