pick a path — it's all one page

Listen & ear-train

hear it, tap it — six quick games

The fastest way to sharpen an ear. Each game plays a sound and asks one thing back — no reading, no lecture. Great for kids and language learners alike.

Say it — pronunciation & speech

you speak, it listens back

Reading a word is not the same as saying it. These surfaces let you speak, hear, and check — turning quiet study into real practice out loud.

Sound library & instruments

the engine — 61 instruments, 1,220 recipes

Under the hub sits a real sound engine — instruments, ambient textures and melodies, all synthesised live in the browser from small recipes. Play them, rate them, or drop one into any page.

Sacred & immersive listening

recorded voice — listen while you work

A recorded voice is the only audio that keeps playing when the screen locks — so this is the spine of long, unhurried listening. Silence is the default; sound punctuates the gaps, matched to meaning, never wallpaper.

Voice & TTS tools

give any text a voice

Turn any written text into listening. The wizard reads long passages in your device’s most natural voice, chunked so nothing cuts off — proof a draft by ear, or give any page a spoken version.

Learn — how sound works

the science behind the listening

Curious what is actually happening when you hear a note, a voice or an echo? A few careful pieces on the physics of sound, with interactive demos.

Work with your voice? A script that reads flat, a character you can't place, an audition with two hours' notice. Find the job you're on and take a prompt written for it.

Why does a text-to-speech voice sound robotic on some devices?VoiceA1

A browser can only speak with the voices installed on that device. When a machine has just one real English voice, a ‘female’ button is often that one voice pitch-shifted higher — which sounds robotic. The fix is to pick the device’s best natural voice, like Edge’s neural en-IN Neerja or Safari’s enhanced Samantha, and let the listener lock it in.

Recorded voice or text-to-speech — which is better?VoiceA2

Can audio keep playing when my screen is locked?PlatformA1

Only a real recorded audio file survives a backgrounded tab or a locked screen. Live sound synthesis and browser text-to-speech are paused the moment the tab is hidden, so recordings are the permanent spine of listen-while-you-work; synthesis and TTS are for foreground preview.

What is a minimal pair?Ear trainingA1

A minimal pair is two words separated by a single sound — ship and sheep, bat and bad. Hearing and saying the difference trains the ear for sounds your first language may not separate, which is exactly what the Minimal Pair Duels game drills.

How many instruments and sounds are in the library?LibraryA1
  • 61 instruments, each with a 20-gesture vocabulary — 1,220 sound recipes in all.
  • 39 nature sounds in the flagship player, synthesised live in the browser.
  • 100-plus nature and ambient recipes in the Wildsong bench.
  • Recorded Gita and hymn audio in Hindi and English, in male and female voices.
How is the nature player’s sound made?LibraryA2

It is synthesised live in the browser from small recipes — rain, waves, birdsong, wind — so each texture loops forever with no audio file to download, and can vary slightly every cycle so a repeat still feels alive.

Why is silence the default in the sacred listening design?Sound designA1

The voice is the hero and sound is punctuation, never wallpaper. A bed that never stops becomes irritating, so sound appears only in the gap between verses — a short, enveloped cue matched to the verse’s meaning — and every verse begins in silence.

Do I need to install anything to use the audio hub?Getting startedA1

No. Everything runs in the browser — the ear-training games, the instrument and sound library, pronunciation practice, and the players. The voice tools speak with the voices already on your device, and let you pick and lock the best natural one.
