Speak turns your words into clear, natural speech. Many of Speak's users have lost their ability to speak, often after surgery, and Speak helps give them a voice again. It's also great for practising pronunciation, or just having fun with voices. Features • Lots of voices: Choose from every voice installed on your device, including Enhanced, Premium and Personal Voice. Search by language, name or region, and preview any voice with one tap. • Fine-tune the sound: Adjust volume, pitch and rate, and repeat a phrase as many times as you need. • Favourites: Save the phrases you use most and reorder them however you like. • History: Every phrase you speak is saved, so you can speak it again or share it. You can also export your history as a CSV file. • Share audio recordings: Turn any phrase into an audio file and share it anywhere. • Make it yours: Light or Dark appearance, a high-contrast text field, and options for how Speak behaves when you type, speak and clear. • Picks up where you left off: Optionally restore your text, voice, pitch, rate and repeat count when you open the app. • Keeps talking in the background: Speech keeps playing while your device is locked or you're using another app. • Louder with Bluetooth: Connect a Bluetooth speaker or headphones to make your voice heard even further. • Works everywhere: No internet connection needed. Supports VoiceOver and iPad multitasking. Quick Tip: If a word doesn't sound quite right, try spelling it phonetically. Speak is free with ads. You can remove them with a single in-app purchase in Settings to support development. Have fun! Feel free to email me with any suggestions or comments at loic@loic.tech.
