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): Portuguese (Portugal) Secondary Language (Required): English – Fluent Participants may be located anywhere globally, provided they are native in Portuguese (ptPT) 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. Portuguese (ptPT): USD 22.00 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 Portuguese (ptPT) is mandatory 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.

THIS IS NOT THE AUTO BID, PLEASE REVIEW IT IN DETAIL I’ve reviewed your project and understand you’re looking for participants with a strong grasp of both Portuguese (ptPT) and English for the multilingual speech data collection initiative. My background in audio engineering and experience with code-switching conversations make me well-suited to contribute effectively to this project. Given the emphasis on natural delivery and context-appropriate language switching, I am prepared to ensure high-quality recordings while adhering to your specifications, including the required sample rates and acceptable speech quality. If selected, I can immediately provide the necessary language verification samples and meet the recording requirements using the specified tools. I'm eager to discuss this further and see how I can enhance your project outcomes. Could you clarify the timeline for the recording phase and any specific preferences for speaker matching? Best regards, Ibad

I’ve recently worked on projects capturing natural bilingual speech patterns where unscripted code-switching was key to authenticity. Instead of focusing solely on language pairing, ensuring genuine context-driven switching preserves the conversational flow and reflects true user experience. Regarding Project BV, I see the need for seamless integration of Portuguese and English within each turn, coupled with technical standards like 25dB SNR and stereo WAV formatting. Done right means recordings feel organic, meet quality benchmarks, and require minimal revisions, keeping momentum steady. I’ve managed complex audio projects balancing tight audio specs and natural speech dynamics, using Zoom and Audacity to control quality risks. Leveraging off-platform tools helped offer tailored pricing without compromising outputs. What I’ll deliver: ✅ Clear, natural code-switch audio adhering to ±10% language ratio ✅ Technical compliance with sample rates and file formatting ✅ Quality checks ensuring minimal noise and distortion ✅ Accurate role pairing without geographical constraints ✅ Streamlined communication to reduce back-and-forth What’s your preferred method for verifying fluent language delivery early in the process? I’d welcome a quick exchange to align expectations. Happy to discuss this further and align before moving ahead. Kind regards Eliza.
