We run speech recording, transcription, and dataset delivery workflows tailored to your technical requirements, from targeted recruitment to structured output.
Most voice products serve fewer than 30 of the world's 7,000+ languages.
Spirelight closes that gap.
Vetted speakers in the right languages, dialects, and age bands record straight from our browser-based capture tools. No extra apps, no third-party software, no fragmented workflow.
Watch every hour land, then pull validated batches straight into your pipeline whenever you need them. No waiting for final delivery to start training.
Some teams need more than generic annotation or off-the-shelf audio. They need the right speakers, the right scenarios, the right formats, and a workflow that holds together from collection to delivery.
Remote or on-site recording projects with targeted contributors, configurable prompts, and controlled capture flows.
Manual, machine-assisted, or hybrid transcription with review layers, timestamps, and speaker-aware structure.
Audio, transcripts, metadata, and manifests packaged to match your pipeline. Click any field to see how it's structured.
Source speakers by language, dialect, location, age, gender, or project-specific criteria.
Configure monologues, dialogues, dual-channel capture, audio plus video, or structured prompt flows depending on the task.
Avoid workflow fragmentation by handling recording, transcription, QA, and packaging in one production chain.
Review files while the project is running and catch issues before they become delivery problems.
Built for projects that need to move fast without becoming generic.
A strong fit for multilingual and dialect-sensitive projects across European markets.
Many projects do not fail because the idea is wrong. They fail because the data is too broad, too noisy, badly structured, or impossible to reproduce. We work at the level where those details matter.
We source speakers by language, dialect, location, age, and gender. Whether it's controlled recording on-site or distributed remote capture, we handle the recruitment and execution.
Built for technical speech requirements. We configure monologues, dialogues, dual-channel capture, and noise environment checks before any recording begins.
Manual, machine-assisted, or hybrid transcription with multiple review layers. We catch issues while the project is running, not at the end.
Audio, transcripts, and metadata packaged to match your pipeline. We deliver via bucket transfer or direct API handoff with full manifest validation.
Command phrases, in-car scenarios, multilingual prompt sets, and structured dialogue data for voice interfaces across regions and accents.
Trigger word collection across demographic groups with controlled recording conditions and environmental variation.
Cross-language training data for virtual assistants covering multiple European languages and regional variants.
Dialogue capture with role-play scenarios, separated speakers, and real conversational variation for customer interaction systems.
Combined audio and video capture with controlled consent flows and structured research delivery for assistive technology.
Domain-specific audio with timestamped transcription output for speech-to-text system testing and improvement.
Controlled scripts, expressive prompts, higher fidelity requirements, and linked speaker metadata for text-to-speech training.
Language coverage projects targeting specific dialect regions with metadata-rich speaker profiles and geographic targeting.
