About

AfterQuery is an applied research platform designed to create high-quality training data for frontier artificial intelligence models by capturing how real experts think, reason, and solve problems in professional contexts. It focuses on transforming real-world work into structured datasets that go beyond simple outputs, encoding decision-making processes, tradeoffs, and contextual reasoning that traditional internet-sourced data cannot provide. It works directly with domain experts to generate supervised fine-tuning data, including prompt–response pairs and detailed reasoning traces, as well as reinforcement learning datasets with expert-designed prompts and grading frameworks that convert subjective judgment into scalable reward signals. It also builds custom agent environments across APIs and tools, enabling models to be trained and evaluated in realistic workflows, and captures computer-use trajectories that demonstrate how humans interact with software step by step.

About

SpeechData.ai is a commercial catalogue and collection service for conversational speech data used to build and evaluate ASR, TTS and other voice-AI systems. Its website lists 60 conversational datasets across 60 languages and dialects, totaling 73,000 audio hours from 7,250 speakers. Listings describe spontaneous two-person recordings, dual-channel audio, time-aligned human-verified transcripts, speaker metadata and consent documentation, with catalogue prices of USD 60–95 per audio hour. Buyers can request samples and commission additional collection to a brief. The provider also offers transcription and audio annotation. Typical buyers include teams sourcing speech for model training and evaluation. Dataset availability, licensing and final price depend on language, collection scope and the terms agreed for the project.
