Is there any way we can convert text to speech in an iPhone app? Is it possible using the SDK?

Although still in beta iOS 7 is public now and includes the class AVSpeechSynthesizer that can be used for text-to-speech. Reference. – Beni 10/9, 2013 at 7:54

voted for reopen, ios7 now is public. use the built in AVSpeechSynthesizer – Blumenthal 30/9, 2013 at 20:22

Now possible. Look at my answer here: https://mcmap.net/q/339273/-voice-output-in-ios – Gaiser 23/12, 2013 at 17:11

I don't think iPhone SDK provides any TTS facility internally. You should use a third party TTS engine or write one yourself.

Not true anymore. iOS 7 introduced AVSpeechSynthesizer. – Gaiser 23/12, 2013 at 17:8

@Gaiser Thanks for the comment! Seems like you're on top of the latest SDK. It'd be great if you could edit the old post with appropriate details (or post a new, updated, answer). – Gabriel 26/12, 2013 at 5:54

see my previous comment to the question. I cannot post a new answer to this question, because it is closed. I posted a code example in this answer to a different question: https://mcmap.net/q/339273/-voice-output-in-ios – Gaiser 26/12, 2013 at 18:1

The Flite speech synthesis engine can be run on an iPhone, ref http://artofsystems.blogspot.com/2009/02/speech-synthesis-on-iphone-with-flite.html

The github repository for the Flite speech engine can be found here: github.com/jeska/eyesfree_dev/tree/… – Jacobine 26/2, 2011 at 17:54

OpenEars also does text-to-speech on the iPhone (note: I'm the developer).

I've found this to have a very nice documentation, specially for first adopters of Xcode, where they need to know how to link it as a library. Many thanks and kudos. – Charmian 27/11, 2011 at 5:29

I'm probably bumping a dead thread but the Flite text-to-speech engine worked wonders for me!

Hope it helps!

were you able to add new voices to the flite engine? how does the output sound compared to the built-in speech synthesizer API? – Badalona 6/3, 2016 at 6:8

Here's another text to speech:

https://bitbucket.org/sfoster/iphone-tts/

You need to download it and install as an API then you can use it like that :

[fliteEngine speakText:@"Hi there"];                    // Make it talk
[fliteEngine setPitch:90.0 variance:50.0 speed:0.9];    // Change the voice properties
[fliteEngine setVoice:@"cmu_us_awb"];                   // Switch to a different voice
[fliteEngine stopTalking];                              // stop talking

Pretty easy to use once you installed it as an API correctly.

are you able to add custom voices to the engine? thanks for sharing! – Badalona 6/3, 2016 at 6:15

good question. I don't think you can though. You'd have to dig deep into the engine I'm not even sure how one would approach this. – Fransis 19/7, 2016 at 17:51

ok thanks anyway ... have you found any good open source code for voice conversion (as opposed to TTS)? – Badalona 19/7, 2016 at 18:39

I wrote a wrapper around pocket sphinx and flite, you should be able to check it out pretty quickly.

Thanks. Am already using this for another project I have :) – Bravissimo 18/5, 2010 at 11:53

Glad to hear it! I'd love any feedback you have. – Serpent 19/5, 2010 at 19:11

hi brian are you able to add new voices using your wrapper? – Badalona 6/3, 2016 at 6:9

The Tomsoft engine is only slow with the custom voices. I'm not sure why. But if you remove the other voices and just the integrated basic KAL voice it will speak almost instanteously. Please send me an email using the contact form on my website if you need any help with this.

Hoya VoiceText is the original provider of the TTS engine. Most of the commercial companies in US create a wrapper around VocieText and resell it.

This was developed by Pentax (LG's spinoff - Korean) which got bought by Hoya (a huge Japanese firm).

Visit here to send a request for the TTS engine: http://voicetext.jp/blog/122.html

Use google translate for English website.

Hoya is based in Japan, but they own NeoSpeech, which is their US provider of the VoiceText Engine. Check out their website for demos.
