call-gpt's Issues

Giving a Knowledge Base for the Bot

Is there any way that we can give a knowledgebase from pdf or any other format

Got the repo kinda working

Right now these are my logs from a recent call

I get no audio on the call, like no audio whatsoever but I do see some transcripts in the console, I honestly can't seem to understand what the issue might be as there are no errors, it seems like deepgram closes conection out of the blue for one thing and also TTS never sends the audio to the actual call. Any ideas?

Interruption handling.

The project is very impressive.

I will break it down to two issues,

1. When we interrupt multiple times to the bot, it generates a new response and then it says the last response but also repeat some of the pending responses before interrupt.
2. Also I think it doesn't wait for the user to complete the sentence, l saw the settings for pause , but sometime user is thinking of right word to complete the sentence, at that time it generates the full response, I think deepgram service needs some changes to handle sentence completion or reply with hmm, yep etc

Wrong inputs in function call

call-gpt/services/gpt-service.js

Line 111 in 9968ade

this.updateUserContext('function', functionName, functionResponse);

The function updateUserContext(name, role, text) has the following order of params, but in the function call when using tools within the gpt-service, you have the ordering as this.updateUserContext('function', functionName, functionResponse); which is (role, name, text). This causes all of the tool fns to throw since it's expecting a role type of function but you are passing in the function name instead.

keeps ringing

setting up Call-gpt went great. but when i call my twilio number i keeps ringing ,no answer then hangs up. On ngrok im getting 200 OK. i did run npm test everything was great. Am i missing something or what could be the problem?

Explicitly order outgoing audio chunks to avoid race condition

We send chunks of text to ElevenLabs that are different lengths. Generally speaking, the STT recordings come back in the right order. But in some circumstances a very short recording might be processed faster than a longer one and arrive first, even though it was meant to be played later.

We should create a cache for ElevenLabs recordings and re-order outgoing recordings to Twilio Media Streams as necessary so that they follow the correct sequence.

Text to Speech is not working !

i have followed every instructions carefully but when i run npm run outbound it works fine for speech to text but it does not respond with text to speech output on call

and i am using

i get this error anyone can tell me how can i solve this!

Deepgram for TTS

I got Deepgram to somewhat work for TTS but it only supports "mulaw" which works with twilio but there is an odd click/noise each time a new audio file starts playback.

Anyone been able to get it to work smoothly? maybe encoding the chunks and then sending to base64 ?

Deegram these days is a much better choices then 11lab, cheaper and faster for TTS.

Just added typescript support for the repo and typed most of the files

Wanted to ask if I can make a PR adding typescript and typings in general, also moving away from require to import, and adding a dist and build folders, just tested and it seems to run fine, who can I ask permissions to push a branch and open a PR if this is a wanted feature?

Getting click sounds and static sounds on the phone when run.

I am getting just click sounds and static sounds the one you get when you tap the mic and then nothing.

Any reason why this is happening?

how i can run this code and voice call to gpt

anyone can quickly tell me how i can run this code that i can conversation to gpt on my phone number
i also follow the steps of readme.MD i have run the server of using (npm run dev
) this command then i run this command (twilio phone-numbers:update +1[your-twilio-number] --voice-url=https://your-server.ngrok.io/incoming
) and then i make call of my number to twilio number but after one 1-2 second call has drop and chatgpt
donot connect with me ?? any one that can tell how i can run the code and how i talk to gpt

1s Latency Definitiion

Tried out the project, very impressed. Thanks for open sourcing. Quick question on latency.

Noticed a minimum latency of at least 3-4s. I am measuring latency as delay between when the human speaks and when the AI responds. This was with everything deployed on fly.io in Ashburn using the exact demo as instructed.

Looks like the biggest bottleneck is the request from Twilio -> Fly.io and Fly.io -> Twilio. Second biggest bottleneck looks like transcription via deepgram.

The ReadMe suggests a latency of 1s—can you clarify the definition of latency here? Is that just looking at gpt response + TTS?

Any ideas on how to reduce latency? Is there a roadmap for this project we can follow somewhere?

Summarize GPT Chat history as more queries are added to the conversation

Currently, responses get increasingly slower as the chat context grows. We should implement a gradual rolloff of older queries that get summarized by GPT and then added to the end of the conversation.

This may require some testing to understand the optimal conversation context size based on quality of results and speed to response.

Training Chatgpt with PDF, Doc or Website Scraper?

Hi, I just come across this project and tested it out. It worked wonder. I am wondering if we are able to train the Chatgpt with our own data such as PDF, Doc , text files or Website Scraper?

Thank you

no response

i can't get it to work. i have set it up on fly.io, got all the api keys, upgraded eleven labs, everything is set in .env. when i call it, it establishes a websocket connection, it gets an incoming request from twilio, it response with the connection endpoint, it opens a new websocket connection, and then nothing happens, or at least i am not getting any reponses. tried everything with chatgpt but i am out of ideas on what the issue could be. any pointers?

I get this issue

when i run "npm run outbound" i get this issue

<Record> Flag on TwiML not working.

So i tried few combination from - https://www.twilio.com/docs/voice/twiml/stream

I tried having the flag set in different location while editing app.js, either errors the app, or does not record on Twilio.

app.post('/incoming', (req, res) => {
  res.status(200);
  res.type('text/xml');
  res.end(`
  <Response>
    // tried here
    <Connect>
      // tried here
      <Stream url="wss://${process.env.SERVER}/connection" Record="true" />
      <Record transcribe="true" playBeep="false" />
    </Connect>
  </Response>
  `);
}); 

Could you please provide the config for vercel deployment

I am trying to deploy to vercel, followed all the instructions available on the internet, but not able to do deploy on vercel, could you please provide config setting to deploy to vercel?

Different TTS models

Great work, thank you for your contribution!

For cost purposes I tried using Neets.ai and Deepgram's TTS but cant get them to work. Terminal seems to log GPT-->TTS but not TTS --> Twilio despite following the docs and matching encoding. Any advice would be greatly appreciated.

Thanks again!
