What's the best speech analytics platform for analyzing call sentiment and topics across support and sales conversations?

There isn’t one universal “best” speech analytics platform for every team, but for call sentiment + topic analysis across both support and sales, these are usually the strongest options:

Best overall for many teams: Gong
