[HEADING=1]Responsible AI considerations[/HEADING]

[HEADING=1]Microsoft [/HEADING]

Microsoft believes that when you create technologies that can change the world, you must also ensure that the technology is used responsibly. Our goal is to develop and deploy AI that will have a beneficial impact and earn trust from society. Our work is guided by a core set of principles: fairness, reliability and safety, privacy and security, inclusiveness, transparency, and accountability. We take a cross-company approach through cutting-edge research, best-of-breed engineering systems, and excellence in policy and governance.

Microsoft is committed to helping our customers use our AI products responsibly, sharing our learnings, and building trust-based partnerships through tools like Transparency Notes and Impact Assessments. Many of these resources can be found at Empowering responsible AI practices | Microsoft AI.

[HEADING=1]Text to Speech service[/HEADING]

As part of this commitment, we have integrated safety and security features and guidelines into Azure TTS Avatar. This includes measures to promote transparency in user interactions, mechanisms to identify and mitigate potential bias or harmful synthetic content, among other features.

In this transparency note, we describe the technology and capabilities for TTS Avatar, its approved use cases, considerations when choosing use cases, its limitations, fairness considerations and best practice for improving system performance.

We require all developers and content creators to adhere to our code of conduct when using avatar features including prebuilt and custom avatars.

To ensure the responsible use of the technology, we have limited access to the custom avatar features. Custom avatars are available by registration only, and only for certain use cases. To access the feature, follow the limited access instructions to register your use case. Besides the limited access, it is required that you obtain explicit permission from the avatar talent prior to creating an avatar model that resembles the actor’s appearance. We require every customer to upload a recorded video file with a pre-defined statement from the avatar talent acknowledging that the customer will use the talent’s image and voice to create a TTS avatar.

[HEADING=1]Content Safety and Watermark[/HEADING]

Azure AI Content Safety is integrated into the batch synthesis process of text to speech avatars for video creation scenarios. This added layer of text moderation allows for the detection of offensive, risky, or undesirable text input, thereby preventing the avatar from producing harmful output. The text moderation feature spans multiple categories, including sexual, violent, hate, self-harm content, and more. It's available for batch synthesis of text-to-speech avatars both in Speech Studio and via the batch synthesis API.

To provide clearer insights into the source and history of video content created by text to speech avatars, we've adopted the Coalition for Content Provenance and Authenticity (C2PA) Standard. This standard offers transparent information about AI-generation of video content. For more details on the integration of C2PA with text to speech avatars, refer to Content Credentials in Azure Text to Speech Avatar .

Additionally, invisible watermarks are added to avatar outputs. These watermarks allow approved users to identify whether a video is synthesized using Azure AI Speech’s avatar feature. Eligible customers can use Azure AI Speech avatar watermark detection capabilities. To request watermark detection on a given video, please contact avatarvoice[at]microsoft.com.
