For sleep stories and guided meditation, EasyVoice offers calm voices — Nicole (Pro), Heart, Emma, and Michael (all free except Nicole) — that hold pacing naturally at 0.85–0.9x speed. Add breathing space with <break> pauses up to 3 seconds, mix a licensed music bed on 128kbps export, and generate full 20–60 minute episodes on the flat Pro plan at $9.99/month.
Sleep and meditation audio is one of the highest-CPM niches on YouTube and Spotify — long runtimes, calm delivery, and loyal audiences that return daily. The voice does almost all the work: a warm, unhurried narrator that stays consistent across 30 to 60 minutes is the single most important production choice.
EasyVoice is built for this format. The Long-Form Studio (Pro) handles 20–60 minute episode lengths in one pass (up to 50,000 characters), speed control dials the voice down to 0.85x without pitch distortion, <break> pauses up to 3 seconds create genuine breathing room between scenes, and licensed music beds mix under the voice on 128kbps MP3 exports. Captions — word-timestamp SRT files — are generated automatically on all Kokoro voices, which includes every voice on this page.
Soft, precise, and extremely clear at slow speeds — the voice real slow-English and meditation creators use on EasyVoice. Pro tier.
Warm American female with a naturally measured cadence — used for guided meditation and sleep stories on EasyVoice. Free tier.
Refined British female with unhurried RP delivery — calm authority for ASMR-adjacent narration and body-scan meditations. Free tier.
Deep, slow American male — Michael's low register and measured pace are physiologically calming for sleep audio and guided breathing tracks. Free tier.
A 20-minute sleep episode is roughly 18,000 characters; a 60-minute one is ~54,000. In Long-Form Studio (Pro), paste the full script and start each scene with a # Scene Title marker — EasyVoice exports one MP3 per chapter.
Start with Michael or Heart (both free). Set speed to 0.85–0.9x for a genuinely slower, more restful delivery — the voice stays natural at reduced speed with no pitch distortion.
Embed `<break time="2s"/>` or `<break time="3s"/>` directly in the script at scene transitions and breath cues. The maximum per break is 3 seconds; chain two breaks for a 6-second pause if needed.
Download the 128kbps MP3 and apply a licensed music bed in EasyVoice (128kbps exports only — beds are not yet applied to 192kbps exports). Or import the dry MP3 into your editor and mix your own bed.
A deep or warm voice that stays natural at slow speeds. On EasyVoice, Michael (am_michael) is the go-to free option — his low register and slow natural pace are physiologically calming for sleep audio. Heart (af_heart) is a warm free alternative; Nicole (af_nicole, Pro) is the softest and most precise at 0.85–0.9x speed.
Set speed to 0.85–0.9x and embed `<break time="2s"/>` or `<break time="3s"/>` pauses at scene transitions and breath cues directly in the script. The voice follows natural sentence cadence at reduced speed — no pitch shift or unnatural pacing.
Yes — EasyVoice mixes a licensed music bed under the voice on 128kbps MP3 exports. Note: music beds are not yet applied to 192kbps exports. Alternatively, import the dry MP3 into any editor and mix your own ambient bed.
