Spirelight.ai

Spirelight.ai collects and annotates speech data for teams building speech recognition, text-to-speech and other voice models. Projects can include speech transcription, time alignment, speaker turns and audio annotation to an agreed brief. Through Speechdata.ai, it also licenses off-the-shelf conversational speech datasets in 60 languages and dialects. These contain spontaneous two-person conversations, dual-channel audio, human-verified time-aligned transcripts, speaker metadata and commercial-use consent documentation. Buyers can request samples using a company email.
