Frequently asked questions
What is Speech models?
Speech recognition or speech-generation models sold as models, not a meeting product. Jobs: asr apis; tts models; speech embeddings.
What should not be listed as Speech models?
Products whose buyer job is meeting assistants, TTS product UIs, or voice-cloning studios. Those belong on their own category page so search queries are not split.
Has AI Trustmark independently assessed every Speech models supplier?
No. A category listing is descriptive. Independent assessment is shown only on company or product pages that carry Trustmark evidence.
What are Speech models?
Speech recognition or speech-generation models sold as models, not a meeting product. Jobs: asr apis; tts models; speech embeddings.
Why do buyers need to know which model providers sit behind an AI product?
Most products depend on named models or APIs. Buyers should identify those providers, where data is sent, and who is accountable when a model version changes. A supplier that cannot name material model providers is not ready for high-assurance procurement.
How can buyers tell whether customer data is used to train models?
Ask whether prompts, files, logs or outputs are used to train, fine-tune or evaluate models, including by subprocessors. Require the contractual default, any opt-out, and whether the setting can be changed silently. Treat marketing 'we do not train' claims as unverified until evidenced.
What model or provider changes should a buyer insist on being told about?
Material change usually includes a new model family, new region, new subprocessor, new write-capable tool, or a change that affects logging, privacy or human oversight. Those changes should trigger evidence refresh rather than a silent release.
How should buyers verify where AI customer data is processed?
Ask for the named processing locations, cloud regions and any subprocessors that see prompts, files or outputs. A directory listing is not evidence of residency. Independent assessment records the locations that were in scope on the assessment date.
