African-language AI calls for respect for the people, cultures, and linguistic communities whose data, knowledge, and participation make this work possible. These considerations inform how Sauti Labs approaches research, data, and AI systems.
01 / Foundation
Sauti Labs works towards African-language AI systems that support speech and language understanding, generation, and related applications. We recognise that the development and use of these technologies carry responsibilities alongside their potential benefits.
Our responsible AI approach applies to the research questions we pursue, the datasets and language resources we assess, the models and outputs we work with, and the third-party AI tools used in our work where applicable.
We consider responsibility alongside technical capability. Privacy, linguistic representation, data permissions, evaluation quality, safety, and transparency are relevant to how we assess research and development decisions. The measures appropriate to a particular activity depend on its purpose, maturity, risks, and available evidence.
02 / What guides us
These principles guide how we reason about data, research, model development, evaluation, and potential applications. They provide a shared basis for examining trade-offs, recognising limitations, and considering the people affected by our work.
We approach AI as a means of supporting human capabilities and informed decision-making, not as a substitute for human judgment in every context. We consider how people understand, interact with, and rely on AI-generated information, particularly where its use can affect important decisions.
We treat African languages, dialects, accents, and communication contexts as distinct and important parts of language technology research. We consider whose language varieties are represented in the resources we work with, where evidence is limited, and how differences in representation can affect system performance.
We recognise that speech and language resources can contain personal information, identifiable voices, and sensitive material. We consider provenance, permissions, consent where applicable, data minimisation, and privacy risks when assessing information for research and development.
We recognise that speech synthesis, voice cloning, and language models can enable both beneficial applications and harmful uses. We consider foreseeable misuse, including impersonation, deception, harassment, and misleading generated content, when assessing technologies and their potential applications.
We distinguish demonstrated capabilities from research objectives and unverified assumptions. We communicate relevant limitations and uncertainty, describe the scope of available evidence, and avoid presenting a model, method, or result as more capable or reliable than the evidence supports.
We treat responsible AI as an ongoing part of technical and research decision-making. We value clear documentation, evidence-based review, constructive feedback, and the willingness to revise decisions when new evidence, limitations, or concerns emerge.
03 / Respect and stewardship
Language data is not merely a technical resource. It can contain personal information, identifiable voices, cultural knowledge, and material contributed by people and communities with different expectations about how it should be used.
We consider the origin, provenance, permissions, licensing conditions, and appropriate uses of data when assessing resources for research and development. Where consent is required or forms part of the conditions governing a resource, we account for its scope and the purposes to which the data may be put.
We distinguish access to data from permission to redistribute it, publish it, use it for model training, or apply it to another purpose. We also consider data minimisation, sensitive information, and the limitations of removing direct identifiers from speech and language resources.
We recognise language communities as more than sources of data. Their linguistic knowledge, experiences, and perspectives matter when identifying research priorities, interpreting results, understanding local context, and assessing the potential effects of language technologies. We consider community perspectives alongside technical evidence when they are relevant and available.
04 / Evidence and limitations
Model performance can vary across languages, dialects, accents, speakers, recording conditions, and real-world contexts. Results for one language or evaluation dataset do not automatically establish performance in another. This is particularly important for African languages, where available data and evaluation resources can differ substantially.
We consider the relationship between an evaluation method, the task being assessed, and the claims supported by the results. Relevant questions include which language varieties are represented, what conditions are tested, which failure modes remain possible, and how uncertainty affects the interpretation of performance.
We treat benchmarks and demonstrations as evidence with a defined scope, not as universal proof of capability. Where evaluation results or research findings are discussed, their methodology, limitations, and context matter. Any disclosure of results also takes account of privacy, licensing, security, and other relevant restrictions.
Convincing generated speech or text is not, by itself, evidence of accuracy, reliability, fairness, or suitability for a particular use. We distinguish the quality of an output from the evidence needed to support broader claims about a system.
05 / Risk and responsible use
Speech and language technologies can support communication, accessibility, education, and creative work. They can also facilitate impersonation, deception, harassment, manipulation, and other harmful uses. The potential benefits of a technology do not remove the need to consider how it could be misused.
We consider foreseeable risks in relation to a technology's capabilities, intended applications, and surrounding context. For speech synthesis and voice cloning, relevant concerns include consent, impersonation, disclosure, the misuse of identifiable voices, and the potential for generated audio to mislead listeners.
We distinguish identifying a risk from demonstrating that the risk has been adequately controlled. The safeguards appropriate to a particular system depend on its capabilities, deployment context, potential consequences, and maturity. Where risks are identified, they inform how the technology and its possible uses are assessed.
No single safeguard eliminates every form of misuse. We therefore consider safety in context, remain attentive to known limitations, and take relevant evidence and feedback into account when reassessing risks.
06 / Continuous responsibility
Responsible development requires the ability to recognise mistakes, respond to concerns, and revise decisions when necessary. We value clear technical reasoning, documented research methods, and evidence that makes important assumptions and limitations open to examination.
We recognise that responsible AI involves technical, linguistic, social, and governance considerations. The questions raised by a dataset, research experiment, model, or potential application are not always the same. We consider these differences when assessing our work and determining which concerns require further attention.
We welcome constructive feedback from researchers, developers, language communities, and others affected by AI systems. Feedback and new evidence are valuable when they clarify limitations, reveal overlooked risks, challenge assumptions, or identify ways to improve the quality and responsibility of our research.
