Japanese Text to Speech: Free, Natural AI Voices
AnyVoice turns Japanese text to speech in seconds — free, no account, nothing stored. Type kanji, kana or mixed text, pick a male or female voice, and download the MP3. It converts text into audio, not the reverse.
Japanese AI Voices by Use — Listen Before You Choose
Japanese has one standard accent, so the real choice is register: a voice that suits a podcast rarely suits a support line. Pick the job first, then the voice.
The free voices run on the engine at the top of this page. Studio voices add emotion and stability controls. Tap play for a sample, or tap a free voice to load it into the generator.

Use this voiceHow to Convert Japanese Text to Speech in 3 Steps
No installs, no account. Kanji, hiragana, katakana and romaji brand names all go in the same box.
- 1
Step 1 — Paste kanji, kana or mixed text
Drop your script into the editor at the top of the page. Use 。 and 、 as you normally would — the voice pauses on them, and a script with no punctuation runs together.
Fix a reading before you generate
Names and place names are the usual traps. Write the kana in brackets right after the word — 東海林（しょうじ）— and the voice reads the kana instead of guessing.

Step 2 — Pick a voice for the register
Open the voice picker and choose by job: narration, conversation, teaching or business. A polite です・ます script sounds best on a narration or business voice; plain-form scripts suit the conversational ones.
Which speed sounds natural in Japanese?
Japanese narration runs around 300–350 characters a minute, which feels slower than English. Keep narration at 0.9–1.0×, push news reads to 1.1×, and drop to 0.8× for learners.

Step 3 — Listen, then download the MP3
Press Generate, play the result, and hit download. The file lives only in your browser — nothing is uploaded to our servers.
Need WAV or a longer script?
Use the text to speech MP3 converter for longer passages, or open the full studio for premium voices and WAV export.
Register, Dialect and Tone in Japanese TTS
About 123 million people speak Japanese natively, and more than four million study it abroad — a record, according to the Japan Foundation's 2024 survey. Almost all of them read and write the same standard Japanese.
Japanese text to speech therefore lives or dies on register and pitch, not regional accent. Four things shape how a script sounds, and the text controls three of them.
Polite (です・ます) vs. plain (だ) — the voice follows the text
「行きます」 and 「行く」 mean the same thing at different distances. A voice reads whichever you wrote, so match the form to the audience: polite for customers and narration, plain for vlogs, monologues and friends.
Tokyo pitch accent — 雨 vs. 飴, 橋 vs. 箸
Japanese words are told apart by pitch, not stress. 雨 (rain) falls on the second mora, 飴 (candy) rises. Our voices use the Tokyo pattern that standard broadcast Japanese uses — the safest choice for any national audience.
Kansai and other dialects
Kansai speech flips several pitch patterns and swaps endings — 分からへん for 分からない, 〜や for 〜だ, おおきに for thanks. Every voice here speaks standard Japanese; you can write dialect words into a script, but the melody stays Tokyo.
Honorifics and customer-facing scripts
Set phrases such as いらっしゃいませ and 〜でございます read naturally, which is why business voices work well for IVR menus and store announcements. Keep sentences short: keigo stacks quickly, and long clauses get hard to follow aloud.
Which voice should you pick for each script?
| Scenario | Register | Voice type | Try |
|---|---|---|---|
| Store or phone announcements | Keigo (敬語) | Business | Kyoko, Makoto |
| Audiobooks, documentaries | Polite narration | Narration | Jin, Shiori |
| Short videos, vlogs | Plain form (だ) | Conversational | Akari |
| Courses, tutorials | Polite, slower | Educational | Satoru, Nanami |
Getting Kanji, Numbers and Pitch Right
A voice reads what you wrote, not what you meant — and in Japanese, one character can be read five ways. Before you run Japanese text to speech on a script, check these five things.
Kanji with more than one reading
生 · 今日 · 東海林いきる / なま / せい · きょう · しょうじCommon kanji such as 生 and 行 carry a dozen readings, and the voice picks by context. Names and places are guessable at best — 東海林 is しょうじ, 日暮里 is にっぽり — so write the kana in brackets after any name you care about.
Counters and dates
1本 · 3本 · 6本 · 4月4日いっぽん · さんぼん · ろっぽん · しがつ よっかCounters change the number's sound: 1本 is いっぽん, 3本 is さんぼん, 6本 is ろっぽん. Dates have their own set — 1日 is ついたち and 4月 is しがつ. Always write the counter after the digit so the voice knows which set to use.
Same sound, different word
はし箸 · 橋 · 端Chopsticks, bridge and edge all sound like はし and differ only by pitch. Write the kanji, not the kana, and the sentence around it tells the voice which pitch pattern to use.
Long vowels and double consonants
おばさん · おばあさん · きて · きってaunt · grandmother · come · stampOne extra mora changes the word. Keep long vowels (ー, あ, う) and small っ exactly as written — a dropped character is the most common source of a wrong reading.
Katakana loanwords and brand names
Google · Costco · IKEAグーグル · コストコ · イケアJapanese has its own readings for global brands, and they are not the English ones. Write brands in katakana when you want the Japanese reading, and leave them in Latin letters when you want them said in English.
Quick fix before you generate
Bracket the kana after names, write counters after digits, put brands in katakana, and end every sentence with 。. Four habits, and most misreadings disappear.
What Can You Do with Japanese Text to Speech?
Four jobs people bring to this page every day.
Narrate podcasts and audiobooks
Japan's audiobook market was projected at about ¥26 billion for 2024, up 86% on 2021. Use a narration voice at 0.9×, generate chapter by chapter, and keep each chapter under the character limit.
Voice videos and localize for Japan
More than 11,000 Japanese YouTube channels have passed 100,000 subscribers. Voice the same script with a conversational voice for shorts and a narration voice for long-form, then drop the MP3 into CapCut or any editor.
Practice listening and reading
Paste a passage, slow it to 0.8×, and read along — the voice resolves kanji you are unsure of. Pair it with a furigana tool and you have a listening drill for any text, not just textbook audio.
Make content accessible
Japan's 2019 Reading Barrier-Free Act pushes publishers toward audio and accessible formats. Turn notices, menus and articles into clear standard-Japanese audio for readers who prefer to listen.

Japanese Text to Speech Tips and Common Mistakes
Small habits that make a generated voice sound like a person who meant it.
A 20-second checklist before you export
Do
- End every sentence with 。 and break long clauses with 、 — pauses land where a reader expects them.
- Bracket the kana after names and place names: 東海林（しょうじ）.
- Write counters and dates in full — 3本, 4月4日 — never as bare digits.
- Match the register to the voice: keigo scripts on business voices, plain form on conversational ones.
Don’t
- Paste a wall of text with no punctuation — the voice never breathes.
- Expect a Latin-letter brand name to get its Japanese reading; write グーグル if that is what you want.
- Run a plain-form vlog script on a formal business voice, or the reverse.
- Judge a voice at 1.5× — test at the speed you will publish.
