Additionally, many of these generative AI tools come with features to make enterprise-level collaboration and content creation run more smoothly. Text to Speech As the term implies, text-to-speech is a type of AI technology that changes written text into spoken audio. Most AI voice generator software enables users to use text prompts in various lengths and languages, which are then processed to produce a spoken version of the content. Voice Cloning With voice cloning, AI technology can capture the content, tonality, speed, and other characteristics of a person’s voice in a recording and use that information to create a faithful replica—or clone—of their voice. With this capability, users can generate entirely new content and recordings that sound as though they were spoken by said person. Custom Voices or Voice Changing With some AI voice generation tools, users can submit a voice clip or record their own voice directly into the app and then modify it to sound like a completely different character. This is typically done by making adjustments to tone, accent, mood, and other vocal traits within the platform. Many users find this feature valuable for creative projects, such as video game development. Multilingual Voice Library Most generative AI voice tools give users access to a diverse, multilingual library of predeveloped voice models. Because the pronunciation and intonation of speech often differ between languages, these tools ensure that each language is represented accurately. This allows users to create more natural-sounding voice recordings that respect the unique characteristics of each language’s speech patterns. Dubbing and Translation Taking TTS a step further, dubbing and translation with AI support the work to translate an existing text or voice recording into a different spoken language. For dubbing specifically, existing recordings—often movies, commercials, and other visual media—are given a new voice track, typically in a different language, generated by an AI model. APIs and Third-Party Integrations With the help of APIs and built-in third-party integrations, users can more easily add AI voice creation and editing capabilities directly into their app and product development workflows. A growing number of AI voice tools are adding relevant third-party integrations to creative platforms, as well as social and distribution channels.

How We Evaluated AI Voice Generators To evaluate these AI voice generators and other leaders in this AI market sector, we looked at each tool’s standard and unique features while focusing on the following criteria. Each criterion is weighted based on its importance to the typical business user. Vocal Quality | 30 percent Needless to say, vocal quality, fidelity, and usability are the most important aspects of an AI text-to-voice app. Within this criterion, we evaluated each tool based on the realistic quality of AI voices, the accuracy of AI voice generations, the availability of different voices and languages, and the ability to granularly edit generated voice products. We also considered whether a tool offered users the ability to customize or record their own voices and voiceovers. Enterprise Scalability | 30 percent Enterprise scalability is hugely important for AI voice generators since many companies invest in this type of platform to create global marketing, sales, and product content at scale. For enterprise scalability, we assessed each tool’s global library of voices and dialects, its adherence to enterprise security and compliance standards, features that enhance voice content production and collaboration, integrations with relevant third-party tools and platforms, and the scalability of APIs. We placed a special emphasis on each tool’s enterprise-level plans and the additional features that are available at this level. Pricing | 20 percent Pricing is a crucial factor when considering AI voice technology, as the cost of these tools varies widely for the features you get at that price point. As part of this evaluation, we compared each tool’s free plan options, how prices scale from package to package, the subscription packages available to users, and the value of the features added to each tier, particularly enterprise-level plans. Ease of Use | 20 percent AI voice tools are supposed to make content creation a simpler task. For this reason, ease of use and accessibility were also important factors in how we judged each of the AI voice generation tools on our list. We looked at each tool’s no-code features, the user-friendliness of voice editing tools, the quality of customer support at each subscription tier, and the availability of self-service resources and community forums for getting started and troubleshooting.
