Yapper
Yapper is a lightweight, offline, easily extendible, text-to-speech library with 136 voices across 39 localities (thanks to the piper project), it can also optionally use SOTA LLMs through their 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

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, PyTTSXSpeaker
that uses pyttsx3 and
PiperSpeaker
that uses piper, PiperSpeaker
is used by default in Yapper
instances. Piper offers many voices in x_low, low, medium and high
qualities. You can use any of these voices by passing a value from the many PiperVoice* (e.g. PiperVoiceUS, PiperVoiceGB, PiperVoiceGermany etc)
enums as the voice argument to PiperSpeaker
and pass the quality you want using the PiperQuality
enum, by default, the voice will be used in the highest available quality. you can subclass BaseSpeaker
to pass your own speaker to a Yapper instance.
from yapper import Yapper, PiperSpeaker, PiperVoiceGB, PiperQuality
lessac = PiperSpeaker(
voice=PiperVoiceGB.ALAN
)
lessac.say("hello")
yapper = Yapper(speaker=lessac)
yapper.yap("<some random text>")
enhancers
an enhancer is a 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, GeminiEnhancer
and GroqEnhancer
, GeminiEnhancer
uses Google's gemini api and GroqEnhancer
uses groq's free APIs', you can create a free Gemini API key or Groq API key to use GeminiEnhancer
and GroqEnhancer
respectively, you can also pass your own enhancer by subclassing BaseEnhancer
. By default, Yapper
instances use the special enhancer NoEnhancer
that doesn't change the text at all, it's used as a placeholder for a real enhancer.
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, GroqEnhancer, Persona
yapper = Yapper(
enhancer=GroqEnhancer(api_key="api_key", persona=Persona.JARVIS)
)
yapper.yap("hello world")
