Training detailThe terms say AssemblyAI may use customer data to develop its products and to train its artificial intelligence and machine learning models. The opt-out is described as applying to the extent of the customer's pricing plan. Customers are also forbidden from using AssemblyAI output to train their own speech models.Cartesia says it uses content to generate output and to train and enhance the models that power the services. Voice or audio recordings are listed as content. You can ask that selected categories of content not be used for future training by submitting Cartesia's online form.The notice says Deepgram uses Content to develop products, including AI model training, unless you opt out. It also says Deepgram may use Content to train and improve its models. When a customer submits other people's audio, Deepgram says it is the processor and this controller notice does not apply.The privacy policy says you can opt out of use of your personal information for training in the Data use menu, and that this only affects training use after you opt out. The terms also say you may opt out of use of your content for training. They also say ElevenLabs obtains publicly available or licensed information to train models. That is separate from customer audio.
How to opt outAssemblyAI points customers to its documentation on opting out of the model improvement program, and says availability depends on the pricing plan. We did not treat that help page as a fact about which plans are included, because this review used the terms for the rule itself.Submit the opt-out form linked from the privacy policy. Cartesia says that after the request is processed, the selected categories are not used to train models in the future. Uses before that date remain.For the APIs, set the training opt-out parameter on the request. That request is then excluded. For Saga, use the opt-out in settings. After that, new Content is not used to train models. Content from before the opt-out is not described as removed from training.In the ElevenLabs account, open Terms and Privacy, then Data use, and opt out of training. The privacy policy says the opt-out does not undo training use from before that change.
