About

IVRS(Interactive Voice Response System) is commonly used platform to reach people connected through mobile/telephones. This page is about how one can set it up and send Voice SMS at any place with minimal requirements. In the school context we can us this software to communicate with parents easily. Most of our school parents are not capable to read sms or letters. from IVRS software we can reach all parents even if they are using basic mobile phones. From IVRS, schools can reach all parents easily by sending voice call. teachers can record their voice message and then send it through IVRS to parents mobile numbers. Same time parents will receive the call and they will hear their recorded message.

Installation and Deployment

This page helps anyone to deploy IVRS to send voice SMS from your Kalpavriksha(Ubuntu) machine with a data card. Call charges as per network would apply. Below instructions were modified from Mojolab site where this was used to install Swara software. This was tested on Kalpavriksha(Ubuntu) with Huwawei E173 and is currently used in Government High School, Domlur. An opensource IVRS program called Asterisk is used to run Swara software.

Contexts

Parents Teachers Meetings

When schools are planning to have parent-teacher meeting at school to dicsuss strudents learning progress, attendence and ther issues, school can use IVRS to invite parents to this meeting. school can request parents through IVRS voice call to participate in Parent-Teacher meeting.

School Level Programmes

Same like parent-teacher meeting school can also communicate parents about school level programmes like National festival celbration, Cultural activities, community meetings, anniversary programmes etc. It will encourage parents to attend school programmes.

Special Classes in School

In schools, for 10th students there will be regular special classess now. and its important to inform parents about special class timings. So that they will be aware about their children and it will help parents to send their children on early hours to school. Same information can send through IVRS voice calls to parents.

Progress Card

School intention is to send progress card to home is to make parents awarded about their children progress. Most of the time students will not show their Progress card to parents and they will make parents signature instead of parents. In this context school can send a voice call through IVRS to inform about progress card issued and request them to see the progress and to make signature.and also school can request parents to meet class teachers if students progress is not good.

Irregular and Slow learn Students

If students are not attending classes regularly, most of the time parents may not aware about it. If school inform parents about their children absents, then parents can enquire and observe their children. and also school can make communication to parents about their children poor learning progress. and here school can insist parents to focus on their children reading at home. School can make list of Irregular and Slow learn Students and can send voice calls to those parents through IVRS.

For Example:Please hear Ejipura school Audio
Please hear Tankgarden school Audio.

To make reading at home

It will help students learning if parents are aware about thier children education. They should always encourage children to engage in reading and writing at home. school can request parents to focus on thier children reading /writing activities at home.

School Admission

Schools may have several activities to increase school strength. One of the best idea is, they can contact nearby HPS schools and can get final class students database with parents contact numbers.

Preparation to use IVRS

1. Need to arrange a data card for school.Generally data cards has been used for internet purpose, but for IVRS we need to have voice call option with outgoing call facility. Internet is required only for IVRS installation and its not essential to run IVRS.
2. Before sending voice calls, we need to think about message and context. its better to script the message.
3. Scripted message can be recorded by using below steps:
   1. We can make voice record by desktop computers. but here head set/mike is compulsory to record. because desktop computers will not have direct input option. in Ubuntu computers we will use Audacity to record.
   2. Through laptops also we can record the voice, here we directly use the ubuntu technology "Audacity" to record the voice.To have good voice recording we must use mike or headsets.

Methods of recording on a computer or laptop

Note to have a conversation with a computer / laptop Application – Sound and Video – Audacity open , then in that by pressing the record button you can record the voice. Next in Audacity to save this recorded voice FILE-Export this you have to select. Here while saving File Format compulsorily .wav format you have to select .From here Export the recorded voice of laptop/computer will be in Downloads folder to VoiceBlast folder.

NOTE : While recording the voice in Audacity the frequency must be set to 8000GHz . see the picture 1
In this way, in audacity toolbar from input channel dropdown select 1.Mono input channel .see the picture 2

ಮೊಬೈಲ್‌ ನಲ್ಲಿ ಧ್ವನಿಮುದ್ರಣ ಮಾಡುವ ವಿಧಾನಗಳು

ಸಂಭಾಷಣೆಯ ಟಿಪ್ಪಣಿಯನ್ನು ಮುಂದಿಟ್ಟುಕೊಂಡು, ನಿಮ್ಮ ಮೊಬೈಲ್‌ನಲ್ಲಿ ರೆಕಾರ್ಡಿಂಗ್ ಅಪ್ಲಿಕೇಶನ್‌ಗಳ ಮೂಲಕ ಧ್ವನಿಮುದ್ರಣ ಮಾಡಿಕೊಳ್ಳಬಹುದು. ಸಾಮನ್ಯವಾಗಿ ಎಲ್ಲಾ ಆಂಡ್ರಾಯಿಡ್‌ ಮೊಬೈಲ್‌ಗಳಲ್ಲಿ Voice Recording ಆಯ್ಕೆಗಳಿರುತ್ತವೆ. ಹಾಗು ಬೇರೆ ಅಪ್ಲಿಕೇಶನ್‌ಗಳನ್ನು ಸಹ ಬಳಸಬಹುದು. ಅದರಲ್ಲಿ “Tape-a-talk” ಎಂಬ ಅಪ್ಲಿಕೇಶನ್ ಉತ್ತಮವಾಗಿದ್ದು ಮೊಬೈಲ್‌ ಪ್ಲೇಸ್ಟೋರ್‌ ಮೂಲಕ ಡೌನ್‌ಲೋಡ್‌ ಮಾಡಿಕೊಳ್ಳಬಹುದು.

ನಿಮ್ಮ ಮೊಬೈಲ್‌ನಲ್ಲಿ Voice Recording ಅಪ್ಲಿಕೇಶನ್ ತೆರೆದು ನಿಶ್ಯಬ್ದವಾದ ಸ್ಥಳದಲ್ಲಿ ಧ್ವನಿಮುದ್ರಣ ಮಾಡಬೇಕು. ನಂತರ ಆ ಧ್ವನಿಮುದ್ರಣದ ಕಡತವನ್ನು ಕಂಪ್ಯೂಟರ್‌ಗೆ ವರ್ಗಾಯಿಸಿಕೊಳ್ಳಬೇಕು. ಕಂಪ್ಯೂಟರ್‌ನಲ್ಲಿ Audacity ಮೂಲಕ ಆ ಕಡತವನ್ನು ಸಂಕಲನ ಮಾಡಿಕೊಳ್ಳಬಹುದು ಹಾಗು .wav ಫಾರ್ಮಾಟ್‌ನಲ್ಲಿ ನಿಮ್ಮ ಕಂಪ್ಯೂಟರ್‌/ಲ್ಯಾಪ್‌ಟಾಪ್‌ನ Downloads ಪೋಲ್ಡರ್‌ನಲ್ಲಿರುವ VoiceBlast ಪೋಲ್ಡರ್‌ನಲ್ಲಿಯೇ ಉಳಿಸಬೇಕು. ಸೂಚನೆ : ನಿಮ್ಮ ರೆಕಾರ್ಡಿಂಗ್ ಅಪ್ಲಿಕೇಶನ್‌ನ ಸೆಟ್ಟಿಂಗ್‌ನಲ್ಲಿ ಆಡಿಯೋ ಪ್ರೀಕ್ವೆನ್ಸಿ ಆಯ್ಕೆ ಇರುತ್ತದೆ ಅಲ್ಲಿ ಆಡಿಯೋ ಪ್ರಿಕ್ವೆನ್ಸಿಯನ್ನು 8000 GHz ಗೆ ನಿಗದಿ ಮಾಡಿಕೊಳ್ಳಬೇಕು.

IVRS ಧ್ವನಿಕರೆ ಕಳುಹಿಸುವ ವಿಧಾನ

1. ಧ್ವನಿಮುದ್ರಣ ಸಿದ್ದಗೊಂಡ ನಂತರ IVRS ಮೂಲಕ ಧ್ವನಿಕರೆ ಕಳಹಿಸುವ ಪ್ರಕ್ರಿಯೆ ಪ್ರಾರಂಭಿಸಬಹುದು.
2. ನಿಮ್ಮ ಲ್ಯಾಪ್‌ಟಾಪ್‌ ಅಥವಾ ಕಂಪ್ಯೂಟರ್‌ ನಲ್ಲಿ ಮೊದಲಿಗೆ ಟರ್ಮಿನಲ್‌ ತೆರೆಯಬೇಕು. ಇದಕ್ಕಾಗಿ ಕೀಬೋರ್ಡ್‌ನಲ್ಲಿ Ctrl+Alt+T ಒತ್ತಬೇಕು. ಅಥವಾ Application Accessories ಮೂಲಕವೂ Terminal ತೆರೆಯಬಹುದು.
3. ಟರ್ಮಿನಲ್ ತೆರೆದ ನಂತರ ಅದರಲ್ಲಿ ಈ ಕೆಳಗಿನ ಕಮಾಂಡ್‌ಗಳನ್ನು ನಮೂದಿಸಬೇಕು.

sudo su
sudo asterisk -vvvvvvc 

ನಂತರ CLI prompt ತೆರೆಯುತ್ತದೆ. ಇಲ್ಲಿ "dongle show devices" ಎಂದು ನಮೂದಿಸಬೇಕು.ಇಲ್ಲಿ Error ಸಂದೇಶ ಕಾಣಿಸಿದಲ್ಲಿ, ನಿಮ್ಮ ಡೇಟಾಕಾರ್ಡ್‌ನ ಸಮಸ್ಯೆಯಾಗಿರುತ್ತದೆ. ಅದನ್ನು ಮತ್ತೊಮ್ಮೆ ಪರಿಶೀಲಿಸಬೇಕು.
ಸೂಚನೆ : IVRS ಇನ್‌ಸ್ಟಾಲೇಷನ್ ಮಾಡುವಾಗ ಬಳಸಿದ್ದ ಡೇಟಾ ಕಾರ್ಡನ್ನೇ ಬಳಸಬೇಕು. ( ಒಂದು ವೇಳೆ ಬೇರೆ ಡೇಟಾಕಾರ್ಡ್ ಬಳಸುತ್ತಿದ್ದಲ್ಲಿ, ಮತ್ತೆ ಕೆಲವು ಸೆಟ್ಟಿಂಗ್‌ಗಳನ್ನು ಮಾಡಿಕೊಳ್ಳಬೇಕಾಗುತ್ತದೆ )

1. ನಂತರ ಮತ್ತೊಂದು ಟರ್ಮಿನಲ್‌ ವಿಂಡೋ ತೆರೆಯಬೇಕು ( Ctrl+Alt+T).ಈ ಟರ್ಮಿನಲ್‌ನಲ್ಲಿ ಈ ಕೆಳಕಂಡ ಕಮಾಂಡ್‌ಗಳನ್ನು ನಮೂದಿಸಬೇಕು

cd Downloads /
cd VoiceBlast 
./VBlast4.py

ಈ ಕಮಾಂಡ್ ಬಳಸಿದ ನಂತರ, ನಿಮಗೆ ಈ ಕೆಳಗಿನ ಚಿತ್ರದಲ್ಲಿ ಕಾಣುವ ಮತ್ತೊಂದು ವಿಂಡೋ ತೆರೆಯುತ್ತದೆ. ಇಲ್ಲಿ ನಾವು ಈಗಾಗಲೇ ಮುದ್ರಿಸಿಕೊಮಡಿರುವ ಸಂದೇಶವನ್ನು ಆಯ್ಕೆ ಮಾಡಬೇಕು, ನಂತರ ಯಾರಿಗೆಲ್ಲಾ ಧ್ವನಿಕರೆ ಕಳುಹಿಸಬೇಕಿರುತ್ತದೆಯೋ ಅವರ ದೂರವಾಣಿ ಸಂಖ್ಯೆಯುಳ್ಳ ಕಡತವನ್ನು ಆಯ್ಕೆ ಮಾಡಬೇಕು. ಧ್ವನಿಮುದ್ರಣದ ಅವಧಿಯನ್ನು ಸೂಚಿಸಬಹುದು.ನಾವು ರೆಕಾರ್ಡ್‌ಮಾಡುವ ಧ್ವನಿಮುದ್ರಣವೂ ಕನಿಷ್ಟ 15 ಸೆಕೆಂಡ್‌ಗಳ ಅವಧಿಗಿಂತ ಹೆಚ್ಚಾಗಿರಬೇಕು.

ನಂತರ SEND ಬಟನ್ ಮೇಲೆ ಕ್ಲಿಕ್ ಮಾಡಬೇಕು. ಈಗ ನಾವು ತೆರೆದಿರುವ ಟರ್ಮಿನಲ್‌ನಲ್ಲಿ ಒಂದರಲ್ಲಿ ಧ್ವನಿಸಂದೇಶ ಕಳುಹಿಸುವ ಪ್ರಕ್ರಿಯೆ ಪ್ರಾರಂಭವಾಗುತ್ತದೆ. ಇದರಲ್ಲಿ ನಾವು ಕಳುಹಿಸಿದ ಸಂಖ್ಯೆಗಳಲ್ಲಿ ಎಷ್ಟು ಜನ ಕರೆ ಸ್ವೀಕರಿಸಿದ್ದಾರೆ ಎಂಬುದನ್ನು ಸಹ ತಿಳಿಯಬಹುದು. ಹಾಗೆಯೇ ಕರೆಸ್ವೀಕರಿಸದ, ಸ್ವಿಚ್‌ಆಪ್ ಮಾಡಿರುವ ಸಂಖ್ಯೆಗಳ ಮಾಹಿತಿಯನ್ನು ಸಹ ನೋಡಬಹುದು.
