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): Swedish (sv-SE) Secondary Language (Required): English – Fluent Participants may be located anywhere globally, provided they are native in one of the primary languages 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 – 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). Payment is split evenly between the two participants. Swedish (sv-SE): USD 20.00 per participant Recording Specifications File Format: Stereo WAV Left channel: Agent Right channel: Customer Sample Rates: 8kHz (telephone quality) – 50% 16kHz – 50% Code-Switching Ratio: 70% primary language 30% English ±10% tolerance Delivery Style: Natural, context-pecific language switching No forced or artificial transitions Speaker Requirements Age Distribution Targets: 18–25 years: 30% 25–40 years: 30% 40–65 years: 20% 65+ years: 20% Gender Balance: 50% male / 50% female Language Proficiency: Fluent English is mandatory; non-fluent speakers will be rejected Participation Limit: Each speaker may participate once only Audio Quality Standards Minimum 25dB signal-to-noise ratio No background noise, distortion, clipping, or echo Quiet, controlled recording environment required Headset or professional microphone strongly recommended How to Apply Applicants should be prepared to provide: * Native language and English proficiency details * Age range and gender * Confirmation of one-time participation * Language verification samples upon request * Participants will be placed in a group chat with others of the same language to work out who will work with whom for the recordings. The project will close once all required recordings are collected. Apply and wait for the next steps if deemed by our team that you qualify. Note: If you do not hear from us, consider that you do not qualify for this project

Hello, and thank you for the opportunity. I am a native-level Swedish speaker and fluent in English, and I am fully comfortable switching naturally between both languages in real-time conversation. I match the exact linguistic profile required for this project. I can deliver: • Clear, natural code‑switching in Swedish ↔ English • Neutral accent, steady pacing, and high intelligibility • Recordings in a quiet environment with clean audio quality • Full compliance with your technical requirements (WAV, stereo channels, 8kHz/16kHz, SNR standards) • Reliable participation, punctuality, and accurate script delivery I am familiar with Zoom recordings and can use Audacity for format conversion and quality checks. I am also comfortable providing language verification samples upon request. I am available to participate as soon as needed and open to being paired with another Swedish speaker for the session. Looking forward to contributing to your ASR dataset.
