This week I worked on getting the simple fill in the blank interface working on the Raspberry Pi. I have the audio input portion working, however have not got the audio output portion working. This is mostly because I have been having trouble figuring out how to get audio to play directly to the speaker as opposed to the built in sound-card. I also ran into some issues with file formats where I assumed that the text to speech package could output .wav files, but it only outputs .mp3 files. Additionally, I found out that the built-in raspberry pi sound card can only support sampling rates of 44056 Hz, 44100 Hz, 48000 Hz, and 96000 Hz.<\/p>\n
I’m behind because I didn’t continue any work on pitch shifting and didn’t get the audio output part of the project working.<\/p>\n
In the next week I hope to start working with Ashika on integrating our two portions of the project as well as finish getting basic user input program working on the pi.<\/p>\n","protected":false},"excerpt":{"rendered":"
