Soshite is fine as a connecting word within sentences, very similar to
"sore kora," used after the "te" form or "to" after a series of nouns for instance.
If you're going to put it after "masu" I think you need to start a new
sentence.
'The voices I can hear' may not be sufficiently clear as an opening
statement but maybe
音声が聞(聴?)こえるんだよ!そして、それらはあなたが好きじゃないです。
