यूएसबी मॉडेम Huawei e1550 के माध्यम से पर्ल पर वॉयस मेनू का कार्यान्वयन

हाल ही में, मैंने एक पोस्ट लिखी जिसमें मैंने थोड़ा सिद्धांत दिया, और एक स्क्रिप्ट के व्यावहारिक कार्यान्वयन का वर्णन किया जो हुंडई e1550 यूएसबी मॉडेम के माध्यम से सूची में ग्राहकों की वॉयस कॉल (अलर्ट) करता है। टिप्पणियों में से एक में, एक सवाल यह पूछा गया था कि एक वॉयस कनेक्शन के दौरान सब्सक्राइबर के फोन पर बटन दबाने पर डेटा कैसे प्राप्त करें। इस मुद्दे के विस्तृत अध्ययन के कारण इस पद का निर्माण हुआ।

यह लेख कार्यों के साथ वॉयस मेनू के कार्यान्वयन को प्रस्तुत करेगा:
- वॉयस मैसेज रिकॉर्डिंग
- सिस्टम कमांड निष्पादित करना
यह सब Goertzel के एल्गोरिथ्म पर आधारित संकेतों के DTMF डिकोडर के कार्यान्वयन के लिए संभव हो गया।
एक बोनस के रूप में - आवाज मेनू स्रोतों का एक संग्रह।

चलिए शुरू करते हैं

कार्यान्वयन में निम्न फ़ाइलें और फ़ोल्डर हैं:
1. voice_menu.pl - आवाज मेनू कार्यों के कार्यान्वयन के साथ मुख्य स्क्रिप्ट
2. dtmf_decoder.pm - dtmf सिग्नल डीकोडिंग के लिए मॉड्यूल (टोन डायलिंग मोड में फोन बटन दबाने)
3. menu.01.pl - इसमें वॉयस मेनू का विवरण होता है
4. menu.01 - menu.01.pl के लिए ऑडियो फ़ाइलों के साथ फ़ोल्डर
5. संदेश - आवाज संदेशों के साथ फ़ोल्डर
