For generating realistic voiceovers and dialog, Eleven Labs stands out as the author's top choice. The platform offers a generous free plan and an affordable starter plan at $5/month, making it accessible for creators. Eleven Labs boasts an extensive library of voices with diverse ages and accents, coupled with intuitive controls for easy audio file modification and download. Initially limited to text-to-speech, the tool has evolved to include a 'voice-to-speech' option, allowing users to upload audio or speak directly to generate custom voices. The author praises the impressive control over pacing and inflection, noting its significant contribution to his AI video projects. With a 5-star rating, Eleven Labs is a highly recommended AI audio tool for speech generation.

Trained on 20,000 hours of licensed music, Meta's Waveformer is a powerful tool that caters to both beginners and technical users. Its advanced AI research background enables the creation of bewildering yet beautiful soundscapes. While users with a background in music, large language models, and Python can leverage its full potential for imaginative audio generation, the author notes that its complexity can be daunting for those seeking simpler solutions. Despite this, Waveformer's ability to generate intricate audio environments is highly impressive, earning it a 5-star rating for its innovative capabilities.

Meta AudioBox is a comprehensive suite of tools dedicated to speech, music, and sound effects, distinct from dedicated music generators. Its voice generator allows users to input desired spoken output and describe voice characteristics and environments. While not yet perfect, the author was impressed with its generation quality, noting the ability to restyle voices and create diverse accents. Its primary utility for the author lies in generating sound effects, from simple door slams to complex prompts like 'water trickling followed by birds chirping,' which yielded samples with great depth and complexity. Despite occasional unexplained error messages, possibly due to heavy usage or developmental stages, AudioBox is rated 4 stars for its potential and versatility.

Suno is recognized for its ambitious goal of enabling anyone to create music, regardless of skill level. The platform can generate songs with music and vocals in a specified style in under a minute, offering two options per generation. While the author acknowledges the significant accomplishment of this technology, he finds the lyrics can sometimes be corny, and the output feels more like a rough prototype than a finished product. Despite a brilliant 'Female vocalist, Torch song, 1940s' generation, a '1970s Soft rock, Ballad' was deemed awful. Suno's cool website and community feature are noted positively. The author expects great things from Suno in the future, rating it TBD due to its current stage of development.
