eSpeak features and specs

  • Open Source
    eSpeak is open-source software, which means it’s free to use, modify, and distribute. This is ideal for developers who want to customize the software or integrate it into other applications.
  • Multi-Language Support
    eSpeak supports a wide range of languages, making it accessible to a global audience. This is particularly useful for projects that require text-to-speech capabilities in multiple languages.

  • Customizable Voice Parameters
    It allows users to tweak various voice parameters such as pitch, speed, and volume, providing some level of customization to the generated speech.

Possible disadvantages of eSpeak

  • Artificial Sounding
    Compared to more advanced text-to-speech systems, eSpeak's generated voice can sound quite artificial and robotic, which might not be suitable for applications requiring natural-sounding speech.
  • Limited Intonation
    The software struggles with natural speech intonation and inflection, making it less ideal for expressive and emotionally nuanced speech requirements.
  • Basic Feature Set
    While eSpeak is functional, it lacks the advanced features found in commercial TTS engines, such as deep learning-based natural language processing and high-quality voice synthesis.
  • Minimal Documentation
    The documentation for eSpeak can be sparse and difficult to navigate, potentially posing a challenge for newcomers or those looking to implement advanced features.
  • Limited Support
    As an open-source project, eSpeak may not offer the same level of professional support or frequent updates that are available with commercial TTS solutions.

  • Show HN: Pi-C.A.R.D, a Raspberry Pi Voice Assistant
    Yes! I'm currently using https://espeak.sourceforge.net/, so it isn't especially fun to listen to though. Additionally, since I'm streaming the LLM response, it won't take long to get your reply. Since it does it a chunk at a time, there's occasionally only parts of words that are said momentarily. Also of course depends on what model you use or what the context size is for how long you need to wait. - Source: Hacker News / over 2 years ago
  • Does anyone know any good TTS program for linux? I'm hoping for something free. There's a good option on windows, but I tried messing with wine to use it on linux and it wasn't working for me.
    You might try espeak or - for something that looks more feature-rich - festival. Source: over 3 years ago
  • I don't know if I'll be able to stream because of my mutism :((
    Hey! I’m mute too and I’ve been wanting to stream. So far I’ve decided on using eSpeak https://espeak.sourceforge.net/, a text-to-speech app for PC that allows commercial usage. You might also be able to find online text-to-speech that allows commercial usage, it just might take awhile to find. Depending on the time of content you make you could also dedicate part of your layout to a spot you could type in and... Source: over 3 years ago
  • Vocaloid 6
    Can someone point to a good open source alternative for vocaloid? I know of Sinsy [0] but I couldn't get it working. Ecantorix [1] is very old and rudimentary (it uses espeak underneath [2]). Searching just now I see OpenUtau [3] but I have no experience with it. Seems crazy there isn't a good FOSS solution for this.

  • Is there a website that reads the custom phonetically written words?
    The closest that I know of is espeak, https://espeak.sourceforge.net/ . It certainly doesn't cover all of the IPA though. Source: almost 4 years ago
