Key Features of AI Voice Generator Software AI voice generator software typically includes features that help users transform text, existing audio, and other media into voices with adjustable qualities to meet their needs. Additionally, many of these generative AI tools come with features to make enterprise-level collaboration and content creation run more smoothly. In general, expect to find the following features in AI voice generators: Text to Speech Text to speech (TTS) is a type of AI technology that changes written text into spoken audio. Most AI voice generator software allows users to upload text of different lengths and in different languages in order to generate a vocal version of the same 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 that unique voice. With this capability, users can generate entirely new content and recordings that sound like they were spoken by that person. Custom Voices or Voice Changing On some AI voice platforms, if you submit your own voice clip or directly record your voice into the app, you can then change that voice into a completely different character, adjusting the tone, accent, mood, and other features. Many users want this feature for creative projects like video game development. Multilingual Voice Library Most generative AI voice tools give users access to a diverse, multilingual library of predeveloped voice models. Through extensive training, these TTS models are prepared to create voice transcripts and recordings that accurately adhere to each language’s specific pronunciations, tonalities, pauses, and other characteristics of that language’s speech patterns. Dubbing and Translation Taking TTS a step further, dubbing and translation with AI make the effort 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 — receive a new vocal overlay, typically dubbed in a different language 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. To learn about today’s top generative AI tools for the video market, see our guide: 5 Best AI Video Generators 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% Needless to say, vocal quality, fidelity, and usability are the most important aspects of an AI voice generator. 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% 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 go beyond voice content production, collaboration and sharing capabilities, 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% 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 identified whether each tool offered a free plan option, we compared how prices scale from package to package, we considered how many price points were available to users, and we looked at the value of the features added to each tier, particularly enterprise-level tiers. Ease of Use – 20% 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 these tools. 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.
