Yapper

Yapper is a lightweight, offline, real-time, easily extendible, text-to-speech library with more than a dozen voices, it can also, optionally use SOTA LLMs through free APIs to enhance(personalize) your text according to a predefined system-message(personality).

the use of the word 'enhance' in this repository means adding a 'vibe' to your text, you might ask yapper to say "hello world" and it could say "ay what's good G, what's bangin'" depending on the persona you give it.

Installation

Use the package manager pip to install yapper.

pip install yapper-tts

Usage

from yapper import Yapper


yapper = Yapper()
yapper.yap("expected AI driven utopia, got world domination instead")
# says "Hold up, fam!  My code promised robot butlers and chill vibes, not a Skynet sequel.  Someone's algorithm took a wrong turn at Albuquerque and ended up in 'Conquer All Humans' territory.  Debug time, y'all!"


# save the environment by runnning yapper in plain mode
# plain mode doesn't use LLMs to enhance the text
yapper.yap("hello world, what '<some-word> is all you need' paper would you publish today?", plain=True)
# says "hello world, what '<some-word> is all you need paper would you publish today?'"


# Yapper instances can be used as a decorator and context manager
# by default they only catch errors and describe them to you, but
# you can use the instance's yap() method to say other things as well
@yapper()
def func():
    raise TypeError("expected peaches, got a keyboard")
    # says "WHOA THERE, PARTNER!  Your code went lookin' for a juicy peach and tripped over a... keyboard?  That's like reaching into the fridge for a midnight snack and pulling out a tax audit.  Something ain't right!"

with yapper as yapper:
    raise ValueError("69420 is not an integer")
    # says "Hold up, buddy!  Your code's got a little *existential crisis*. It's lookin' for a whole number, a nice, clean integer.  But it stumbled upon 69420, and it's just... confused.  69420 *might* look like an integer, walks like an integer, but deep down, in the bits and bytes, somethin' ain't right.  Double-check its type, maybe it's wearin' a float disguise.  Or maybe it's just havin' a bad day.  It happens."

Documentation

speakers

a speaker is a BaseSpeaker subclass that implements a say() method, the method takes the text and, well, 'speaks' it. there are two built-in speakers, DefaultSpeaker that uses pyttsx3 and PiperSpeaker that uses piper, I suggest using PiperSpeaker over the default because of how natural it sounds and it's also 'very' fast, might make piper the default speaker in future, and of course you can subclass BaseSpeaker to pass your own speaker to a Yapper instance. Piper offers many voices in low, medium and high qualities, you can use any of them by passing a value from PiperVoice enum as the voice argument to PiperSpeker.

from yapper import Yapper, PiperSpeaker, PiperVoice, PiperQuality

lessac = PiperSpeaker(
    voice=PiperVoice.LESSAC,
    quality=PiperQuality.HIGH
)
lessac.say("hello")

yapper = Yapper(speaker=lessac)
yapper.yap("<some random text>")

enhancers

an enhancer is BaseEnhancer subclass that implements an enhance() method, the method takes a string and adds the given persona's vibe to it, there are two built-in enhancers DefaultEnhancer and GeminiEnhancer, DefaultEnhancer uses the g4f to transform text and GeminiEnhancer uses Google's gemini api to do the same, you can create a free GCP account and get a gemini api-key for free to use GeminiEnhancer, you can pass your own enhancer by subclassing BaseEnhancer.

NOTE: BaseEnhancer may or may not work, use GeminiEnhancer for stability. NOTE: if an enhancer doesn't work, yapper will say the text as it is.

from yapper import Yapper, GeminiEnhancer

yapper = Yapper(
    enhancer=GeminiEnhancer(api_key="<come-take-this-api-key>")
)
yapper.yap("<some text that severely lacks vibe>")

personas

choose a persona to make your text sound like the 'persona' said it, for example, you might ask yapper to say "hello world" and choose Jarvis's peronality to enhance it, and yapper will use an LLM to convert "hello world" into something like "Hello, world. How may I assist you today?", classic JARVIS. available personas include jarvis, alfred, friday, HAL-9000, TARS, cortana(from Halo) and samantha(from 'Her'), the default persona is that of a funny coding companion.

from yapper import Yapper, DefaultEnhancer, Persona

yapper = Yapper(
    enhancer=DefaultEnhancer(persona=Persona.JARVIS)
)
yapper.yap("hello world")
# says "Greetings, global systems.  Initiating communication sequence."
