As a Python backend developer, I'm looking for someone who can help me build a personal project. This project involves audio, specifically real-time audio processing and analysis. We need this backend for a web app that will send audio data over websocket connection to your backend. Your backend should accept the stream and transcribe it on the server and then store the text in postgresql database and then convert the transcribed text to audio using tts and send it back as a stream to the user over the same ws session/consumer that initiated it. This pipeline should have min latency and hence we prefer using local speech to text and text to speech instead of making external api calls. We could also use external services using apis if the quality of these services is not good - we need high quality transcription and tts. The pipeline components should be modular so it is easy to change or replace components in order to benefit from higher quality apis that become available. If the user starts speaking again (ie if your backend starts receiving audio over the open websocket connection) then the output stream has to be stopped. For this you will need to design a queueing system or any system that can do this. You need to manage the sequencing, buffering etc to ensure that the system works irrespective of traffic congestion and other conditions. Skills and experience needed: - Proficiency in Python and FastAPI and websocket - min 3 years experience - Proficiency in speech to text and text to speech libraries - min 1 year experience - Experience with real-time audio processing - should have worked with real-time audio on 3 projects at least - Strong background in asynchronous programming and asyncio queues - highly experienced in this - Understanding of concurrency handling in web applications - highly experienced in this - Ability to design for scalability - highly experienced in this

Hi There, As a Python backend developer with extensive experience using FastAPI and working with websockets, I am confident in my ability to deliver a high-quality solution for your real-time audio processing project. My expertise with Python is evident through my over 3 years of working experience with the language and specifically with FastAPI. This enables me to handle the websocket connection for audio data in an efficient, low-latency manner. One of the key challenges in your project is the efficient management of concurrency, sequencing, and traffic congestion. Having worked on numerous projects involving real-time audio processing, I have honed my skills in asynchronous programming, asyncio queues, and scalability design which perfectly aligns with this requirement. Additionally, my experience in speech-to-text and text-to-speech libraries ensures that all transcription and TTS conversions will take place locally on the server to minimize latency. However, as you mentioned quality is paramount, I'm adaptable enough to integrate external service APIs if needed while ensuring their modular design makes replacement easy when higher quality providers become available. All points considered together, it’s undeniable that I’m the best choice for this porject! Regards Anamul

As an experienced full-stack professional with a focus on Python, I'm poised to deliver the high-quality, low-latency backend solution your project demands. I have over a decade of experience in software development, including three years proficiently working with Python and FastAPI specifically and a year's experience in speech-to-text and text-to-speech libraries. This makes me well-suited to create your desired audio processing and analysis pipeline using local services. More than just using these tools though, I've worked with real-time audio processing multiple times before - this depth of experience will be invaluable to creating a reliable system for managing the audio streams smoothly. Taking full advantage of my strong background in asynchronous programming, asyncio queues, and managing concurrency in web applications, I will construct a scalable and efficient solution that reduces downtime for better end-user experiences. Additionally, I have an understanding of the importance of scalability so even if you end up deciding on replacement components or adding external services through APIs, the modularity of pitch adapts to these changes easily. Finally, my familiarity with postgreql ensures smooth data handling between conversion processes while maintaining optimum latency levels.
