The industry-standard voice library against OpenAI’s stage-directed speech.
ElevenLabs remains the realism benchmark: 30+ curated voices with natural intonation that hold up across long scripts — the default for narration, audiobooks and podcasts. GPT Audio’s edge is direction: describe the performance («whisper it», «upbeat radio host», «slow down at the end») and it acts the line rather than reading it.
Pricing splits by use: ElevenLabs bills 60 credits per 300 characters — predictable for long scripts; GPT Audio Mini voices whole drafts for a flat 40 credits, and full GPT Audio (160) buys the most expressive acting. Many workflows draft with Mini and finish with ElevenLabs.
Prices are in Nexvy credits — one balance shared by every model on the platform.
